Abstract : A steam heat receiver which is applicable to a 20 KWe solar power system was designed, fabricated, and tested using a 180 KW electrical heat source. The cylindrical heat receiver configuration, utilizing lithium fluoride for energy storage and steam as the working fluid, was established by the Air Force Aero Propulsion Laboratory. The purpose of the test program was to generate data to be used for the development and verification of analytical design techniques. The heat receiver was instrumented to measure thermal gradients and movement of the fusion front during the simulated dark portion (energy depletion) of a 100 minute earth orbit. In the test program, it was found that a pressure excursion occurs upon attempting to establish water flow into the heat receiver. This prevented simulation of the 35-minute energy-depletion portion of the cycle. However, a limited amount of data is presented for low water flow rates. Thermal conductivity tests of small samples of Inconel Feltmetal filled with lithium fluoride are also presented.
