Abstract:

Laboratory tests were conducted on a small scale Fluidyne heat engine in the loaded and unloaded configuration to evaluate the effect of geometric changes on the systems operating characteristics. Liquid column displacements, gas temperature, and pressure were the primary variables measured for various heat inputs and gas volumes. Representative outputs were a pumping rate of 0.0976 galmin through a head of 0.825 ft, with a overall efficiency of .15, and operating pressures as high as 5 psig. The results of the experimental program are presented together with a summary of the principles of operation. Author
