Development of a High Velocity Solid Particle Launcher for Laboratory Erosion Studies. [Reentry Vehicle Heat Shields] (open access)

Development of a High Velocity Solid Particle Launcher for Laboratory Erosion Studies. [Reentry Vehicle Heat Shields]

A solid particle launcher for laboratory erosion studies has been developed and successfully demonstrated. Performance of the launcher is predicted by a two-dimensional, time-dependent theoretical analysis to within the experimental uncertainty. The present device accelerates 100 μm diameter glass spheres to velocities of 2.1+/- 0.6 km/sec. The system is safe, reliable, and has a test repetition of about 2 shots/hour.

Photovoltaic engineering services pertinent to solar energy conversion

The application of the compound parabolic concentrator (CPC) for use with solar cells has been investigated. Experiments with state-of-the-art Si cells in a CPC and under solar concentration were performed. A theoretical model for calculating the behavior of Si solar cells with concentration was developed. Detailed calculations of the energy distribution in the CPC were made. Finally a cost effectiveness analysis shows that the CPC system will produce power at very much lower cost than will flat panel solar cell arrays. (auth)

Prevention of biofouling on heat transfer surfaces of ocean thermal energy converters. Progress report, May 1, 1975--November 30, 1975 (open access)

Prevention of biofouling on heat transfer surfaces of ocean thermal energy converters. Progress report, May 1, 1975--November 30, 1975

The objectives of the program were to develop chemical processes utilizing a combination of certain fluorochemicals and tribulyltin based toxicants for treating the surfaces of metals which may be used to fabricate OTEC heat exchangers, and to demonstrate the effectiveness of these surface treatments as antibiofoulants. Aluminium alloy No. 3003-H14 and titanium were testd, neither of which proved satisfactory. (WDM)

Comparison of solar pond concepts for electrical power generation (open access)

Comparison of solar pond concepts for electrical power generation

The objectives of this study were to: (1) Identify the various solar pond concepts for electric power generation, including but not limited to: (a) nonconvective salt gradient solar pond, (b) ponds with various plastic or other membranes at suitable locations to minimize or eliminate convection, (c) ponds which are totally or partially gelled to reduce or eliminate convection, and (d) shallow convecting ponds; (2) analyze and compare the performance of these various concepts; and (3) estimate the pond cost and overall power plant system cost for each concept assuming the nonconvective gradient salt pond as the base case. The approach includes a preliminary design of several power plant systems based on solar pond concepts, and performance and economic evaluation based on these preliminary designs. (WDM)
