Two successful shock tube experiments were recently performed at the Lawrence Livermore Laboratory. The experiments simulated the high enthalpy flow conditions that might arise in the nuclear blast encounter of a tunnel-based missile. The experiments, using a modified Voitenko high explosive generator, produced megabar pressure conditions at the inlet of the 2 cm-diameter air-filled shock tubes. Computer calculations have been done to model the 10/sup 5/-fold increase in air pressure in the Voitenko generator. These calculations are necessary to describe the source for the experiments and to permit better interpretation of the experimental data. A detailed understanding of the phenomenology of the compressor is also essential for optimization of future experiments, especially those involving scaling up to larger size shock tubes. An arbitrary Lagrange-Eulerian computer code was selected to calculate the late-time high explosive driven motion of a steel plate into the bell shaped compressor section. It was found that ordinary Lagrangian and Eulerian codes had difficulty in properly treating the steel-air interfaces, whereas an arbitrary Lagrange-Eulerian code was capable of modeling the complex flow of air past the steel interfaces in the compressor region. Using an improved equation of state for air, excellent agreement has been obtained in the …

The objective of this document is to outline the test plan for the KIPS Technology Verification Program. This test plan is inclusive of component simulating (rig) testing, component testing and system testing. Rig testing will prove concept feasibility, measure basic performance and to develop the hardware necessary prior to initiation of GDS component part manufacture. Component testing will measure basic performance and verify component integrity prior to GDS assembly. The GDS system testing will: simulate the flight system operation; determine the life limiting components; measure performance and relate to potential system lifetime; demonstrate 18+% DC generating efficiency; and perform a 5000 h endurance test with final configuration hardware.

During this program, the use of energy storage in conventional appliances to save energy was evaluated. Fuel-fired appliances, electric appliances, and utility load leveling by energy storage on the customer's side of the meter were considered. For each of the appliances treated, various energy-storage techniques were evaluated by estimating the energy savings and the cost of the required storage system. An estimate of the commercial feasibility of each system was made based on the years necessary to pay back the cost of the storage system. In addition, when alternate approaches could be used to improve the efficiency of the appliance without energy storage, the costs of these methods were considered in the evaluation. The analyses found that the most-promising applications involved the use of point-of-use thermal energy storage for electric-utility load-leveling. However, although substantial utility operating cost savings can be achieved, there may be little or no actual energy saving when all losses are considered. For applications other than load-leveling, energy savings were too small to pay back the added cost of the storage system in an acceptable time.

Phillips' objectives related to financing a geothermal development are: (1) to make a reasonable profit, (2) to keep risks in line with potential benefits, and (3) to operate in a free and open market. Each of these objectives is discussed briefly. (MHR)

Progress of government-sponsored projects directed toward increasing gas production from the low-permeability gas sands of the western United States is summarized. A Technology Implementation Plan (TIP) meeting was held at the CER office in Las Vegas, Nevada, October 16--19 to initiate the implementation phase of the Enhanced Gas Recovery (EGR) working group activities. A WGSP Logging Program meeting was conducted on October 24, 1978, at CER offices to define the problems associated with logs in tight gas sands. CER personnel and the project manager attended a two-day course on the fundamentals of core and reservoir analysis in Denver, Colorado, and met with USGS personnel to discuss USGS work on the WGSP. A meeting was held to discuss a contract for coring a Twin Arrow well on the Douglas Creek Arch, Colorado. CER Corporation personnel attended the Geological Society of America Annual Meeting held in Toronto, Canada, October 23--27 and a Gas Stimulation Workshop at Sandia Laboratories in Albuquerque, New Mexico, October 11 and 12 to discuss recent mineback experiments conducted at the Nevada Test Site. Fiscal year 1979 projects initiated by USGS and the Energy Technology Centers and National Laboratories are progressing as scheduled. Mobil Research and Development Corporation fractured …
