Hydraulic resistance analyses of selected elements of the prototype Stirling engine

The paper presents the results of simulation tests hydraulic resistance and temperature distribution prototype Stirling alpha engine supplied with waste heat. following elements were analyzed: heater, regenerator cooler. uses compressed air as a working gas. Analyses carried out for three pressure values and different speeds. work was in order to optimize the configuration due minimization hydraulic resistance, while maintaining required thermal capacity device. Preliminary tests on real object allowed determine boundary initial conditions purposes. assumes that there is no heat exchange between environment. The solid model used includes elements: supply channel, heater, regenerator, cooler, discharge channel. Due symmetrical structure analyzed elements, out using 1/6 volume system.
