RESEARCH ON CHARGED ALKALI COLLOIDS FOR AEROSPACE VEHICLE AND GROUND BASED POWER GENERATORS

摘要

A thermodynamic study of two fluid EFD ejector generator systems is presented. A figure of merit is defined which allows comparison of various fluid combinations. An overall cycle optimization leads, for a mercury hydrogen system to efficiencies of the order of fifteen percent. Subsequently, various aspects of conversion process and its limitations are considered including: effect of space charge cloud divergence on generator performance, limitations due to colloid drop size and number density, effect of electron and ion emission from drops, breakdown strength.
