THERMODYNAMIC WORKING FLUIDS FOR STIRLING-CYCLE, RECIPROCATING, THERMAL MACHINES

摘要

the new working fluids for working with primary application to stirling cycle heat engine is a reciprocating movement,.which are more fluid, heat transfer coefficient, dynamic hydrogen or helium, and the chemically inert and easily obtained.a new control system of power level (figure 2).(4) based on the thermodynamic properties of these fluids is described.and it is intended to be used in conjunction with a stirling cycle machine. this new approach greatly simplifies the procedures for the change of the average pressure of worksystem, and thus the instantaneous power level during the operation of such machines.
