THE CONVERSION OF HEAT TO ELECTRICAL POWER BY MEANS OF A CHARGED AEROSOL
Abstract
A new process called the condensation aerosol method for the production of small, charged aerosol particles has been developed for use in the electrohydrodynamic energy conversion process. Using this concept, several generators may be placed in series, each one using the same vapor for aerosol formation as the previous unit. Power densities as high as 30 watts/sq. cm. of nozzle throat area have been obtained with a single stage condensation aerosol type EHD generator. Studies of the aerodynamic behavior of the EHD generator with and without energy extraction were made on a fully instrumented test bench. Measurements of the overall efficiency of the genera tor including frictional losses were made and are reported herein. The kinetic to electric power conversion efficiency of the generator itself was as high as eighty-five percent. Efforts were made toward designing and building a closed loop system for the generator. A small compressor system for circulating a gas in a closed loop was tested. Calculations were made for the de sign of a small boiler system for operating a closed loop steam cycle at a few atmospheres pressure.
