To demonstrate the enhancement of heat transfer in OTEC exchangers by means of fine, axial flutes on the heat transfer surfaces, experiments have been performed on single internally or externally fluted tubes of 1-inch diameter. Internal flutes provide water-side enhancement of both heat transfer and friction to about the same extent. At moderate water velocities heat transfer coefficients and friction factors are greater than those of the comparable smooth tube by a multiplying factor about equal to the fluted-to-smooth surface area ratio. Area ratios from 1.0 to 1.5 have been tested using two styles of flutes. Flute heights have ranged from 3 to 35 mils, tube lengths from 2 to 8 ft. Heat transfer experiments have been performed on Freon-11 moving in a thin layer under gravity down the outer surface of a smooth tube and of a tube having 26-mil external, axial flutes. Test lengths have averaged 4-/sup 1///sub 2/ ft. Enhancement of the local coefficient by 3 to 5 times has been observed during both evaporation and condensation. The effectiveness of the flutes is greatest in the range of laminar-turbulent transition.

This is the eighth quarterly technical progress report for a program in which the objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The current Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: the test vehicle was successfully driven to and from Ann Arbor, Michigan from Phoenix with the drive system installed; accessory drive hardware was calibrated, disassembled and reviewed for wear after round trip from Phoenix to Ann Arbor, Michigan; MADS governor performance was analyzed and parameters were varied to demonstrate flexibility available in modifying accessory drive input/output characteristics; and a task list that matched smaller, lower cost accessory components, with the accessory drive equipped vehicle, was prepared. Major emphasis during the remainder of the program will be in this area. (LCL)

Progress is reported for a research program to demonstrate an experimental gas turbine powered automobile which would meet the 1978 Federal Emissions Standards, have significantly improved fuel economy and be competitive in performance, reliability and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Chrysler Corporation's Sixth Generation Gas Turbine Engine, having been selected as most representative of the state-of-the-art at the beginning of this program, has been used as the Baseline Engine. This is a 4:1 pressure ratio regenerative engine with variable power turbine nozzles which meets the .41 HC, 3.4 CO, 3.0 NOx grams/mile original 1975 emissions standards. Baseline vehicles are intermediate-size, 4-door sedans modified to accept the turbine engines. The Baseline cars are being actively utilized in a variety of Bicentennial/Energy related displays and demonstrations. All Baseline Engine improvement tasks have been completed. Emissions tests using COED coal derived fuel were conducted. The first Upgraded Engine was assembled, installed in a test cell, and initial test runs up to 70% speed were conducted. Control of the gas generator shaft instabilities which have resulted in failures of the gas lubricated bearing, was demonstrated by providing a low spring rate, squeeze film damping, and reducing …

In the management of the adverse byproducts of nuclear energy, the general problem is centered in the post-reactor discharge phases. Various waste streams are generated in the reprocessing and fuel manufacturing plants which add both volume and physicochemical diversity to the nuclear fuel waste management problem. Of these streams, the high level waste (HLW) and the clad waste streams carry the principal radiological hazard and thermal power burdens when considering post reactor-discharge times in excess of roughly a year and reasonable contamination factors. In order to measure the relative importance of the high level and clad waste streams within the context of a reasonable nuclear power scenario, various technical and hazard indices are compared for the light water, enriched uranium fueled, reactor (LWR(U)). For the clad waste, two fuel models are used for the volume comparison: the Reference Fuel Assembly (RFA) and the Diablo Canyon reference fuel model (DC). The more extensive data available for the Diablo Canyon model on radioactivity and thermal power are used in the comparison of these indices. Most of this review pertains to a burnup of 33GWD/MT. A brief analysis is given of the effect of burnup and fuel model on certain clad waste characteristics. …

In this report a method is given for modifying the Monte-Carlo approach so that one can accurately treat problems that involve both large and small mean free paths. This method purports to offer the advantages of the general Monte Carlo technique as far as relatively great accuracy of simulation of microscopic physical phenomena is concerned, and the advantage of a diffusion theory approach as far as decent time steps in thick problems are concerned; it does suffer from something of the statistical fluctuation problems of the Monte Carlo, although in analytically attenuated and modified form.

The Isotec Technology Program for FY-75 concentrated on materials development efforts in two areas: TPM-217 P-type material and SiGe technology. TPM-217 P-type material is a 3M proprietary thermoelectric material whose principal components are Cu, Ag, and Se. The usefulness of TPM-217 P-type selenide in thermoelectric converters depends on its dimensional, electrical, and thermal stability at high temperature and its compatibility with other converter component materials in a low-pressure environment. Experimental efforts were directed toward determining (1) the vapor species above TPM-217 from 700/sup 0/ to 1100/sup 0/C, (2) the weight loss rate for TPM-217 at 900/sup 0/C in vacuo, and (3) the stability of TPM-217 material in contact with Mo, Fe, 316 stainless steel, and pyrocarbon. The Si-Ge program is a continuation of the experimental work performed during FY-74. The development of coatings to suppress the vaporization of SiMo and SiGe continued. Techniques for applying ion-plated and chemical-vapor-deposited coatings of Si/sub 3/N/sub 4/ and (Si,Al)N alloys on SiMo were examined. Methods of controlling morphology and the chemical composition of these coatings were developed. Rates of vaporization for coated samples at 1100/sup 0/C were measured.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

The transpiration of CO through the Multihundred Watt (MHW) filter can be described by Fick's first law or as a first order, reversible reaction. From Fick's first law, a ''diffusion'' coefficient of 7.8 x 10/sup -4/ cm.L/sec (L is the average path length through the filter) was determined. For the first order reversible reaction, a rate constant of 0.0058 hr/sup -1/ was obtained for both the forward and reverse reactions (they were assumed to be equal). This corresponds to a half-life of 120 hr. It was also concluded that the rate constants and thus the transpiration rates, which were determined for the test, are smaller than those expected in the IHS. The effect of increasing the number of filters, changing the volumes, and increasing the temperature, changes the rate constant of the transpiration into the PICS to roughly 0.074 hr/sup -1/ (t/sub /sup 1///sub 2// = 9.4 hr) and out of the PICS to 0.84 hr/sup -1/ (t/sub 1/2/ = 0.8 hr). Of the two suggested mechanisms for the generation of CO inside the IHS, the cyclic process requires a much larger rate of transpiration than the process requiring oxygen exchange of CO given off by the graphite. The data …

In the tritiated liquid waste decontamination by molecular excitation studies, further calculations were performed on the hydrogen atom-water exchange reactions. Assembly and testing of the cell to be used for the measurement of the HTO IR spectrum were completed. As a result of findings from trial loadings using HD as a surrogate for HT in the oxidation system, it is believed that larger quantities of HTO will be required to obtain the desired ir spectrum. This appears to be a result of a significant adsorption of the water on the inner surface of the spectrometer cell. In the catalytic exchange detritiation studies, leak checking and cold operational testing of the experimental apparatus were completed. Modifications were made to improve the operability and reliability of the system as originally designed by Engelhard Minerals and Chemicals Corp. A computer program was prepared for the calculation of twelve hydrogen isotopic compounds in thermodynamic equilibrium. This program based on the free energy minimization technique produced data on the equilibrium concentrations of tritium compounds from reactants with various T/D/H/O ratios (e.g., T/H = approximately 10/sup -8/ to approximately 10/sup -2/) at temperatures ranging from 300 to 800/sup 0/K. The bourdon tube pressure gage on the …

The transport equation may be solved by expanding it in spherical harmonics, Y{sub lm}, and truncating the resultant infinite set of equations at some finite order L. This procedure leaves the (L + 1)th order moments which appear in the Lth order equation undetermined, and the standard procedure for obtaining a closed set of equations has been to set all the (L + 1)th order moments to zero. It has been shown here that this procedure actually violates the apriori knowledge that one is solving for the moments of a probability measure on the unit sphere. Using the theory of moments of a probability measure on the unit sphere. Using the theory of moments as discussed above, the (L + 1)th order moments can be chosen in accordance with apriori knowledge. The resultant truncated set of equations has properties much truer to the original transport equation than the usual set obtained by setting the (L + 1)th order moments to zero. In particular the truncated set of equations gets the solution of the transport equation exactly right in both the diffusion limit and the free streaming limit. Furthermore, this has been achieved by merely truncating the set of equations properly …

The nation's transportation system faces problems on both sides of the supply-demand equation. Analysis of these problems has resulted in identification of two broad transportation energy conservation program areas: (1) more-efficient and environmentally acceptable heat engine systems are needed; they must be optimized for available fuels and eventually alternate fuels; and (2) alternate propulsion systems such as electric or hybrid vehicles are also required. A difficulty arises in that these solutions may not come about in a timely fashion due to market forces alone. It is necessary to understand why this is so in order that appropriate government actions can be taken. Discussed first is a fundamental premise or assumption that the public good is best served by a free market which presumably allocates resources optimally; in other words, for the greatest positive net social benefit. Optimal resource allocation is considered synonymous in this discussion with conservation. This fundamental assumption has been challenged in that, if public and private objectives diverge, sub-optimal resource allocation could result with attendant social disbenefit. This divergence of objectives can come about in the transportation sector in two ways. First, when the market value of energy is below the true marginal value, markets will tend …

A method for calculating quasi-one-dimensional, steady-state, two-phase dispersed droplet-in-vapor flow has been developed. The technique is applicable to both subsonic and supersonic single component flow in which normal shock waves may occur, and is the basis for a two-dimensional model. The flow is assumed to be inviscid except for droplet drag. Temperature and pressure equilibrium between phases is assumed, although this is not a requirement of the technique. Example calculations of flow in one-dimensional nozzles with and without normal shocks are given and compared with experimentally measured pressure profiles for both low quality and high quality two-phase steam/water flow.

Large aperture, beryllium substrate-based mirrors have been used to focus high intensity pulsed laser beams. Finished surfaces have high reflectivity, low wavefront distortion, and high laser damage thresholds. This paper describes the development of a series of metallic coatings, surface finishing techniques, and dielectric overcoatings to meet specified performance requirements. Beryllium substrates were coated with copper, diamond-machined to within 5 micro-inches to final contour, nickel plated, and abrasively figured to final contour. Bond strengths for several bonding processes are presented. Dielectric overcoatings were deposited on finished multimetallic substrates to increase both reflectivity and the damage thresholds. Coatings were deposited using both high and low temperature processes which induce varying stresses in the finished coating substrate system. Data are presented to show the evolution of wavefront distortion, reflectivity, and damage thresholds throughout the many steps involved in fabrication.
