Summary
Four existing computer codes for Stirling cycle machines were run and the computational results are compared with experimental data for two laboratory test engines. Representative codes were selected to compare the fast type of simplified second-order analysis with the more detailed third-order analysis which includes dynamic effects in the fluid mechanics equations. A comparison is also made with the closed-form, first-order Schmidt analysis. The baseline test engines are of the straight-through design type. The Kim-engine, a single-piston highly idealized apparatus designed chiefly for the study of regenerator performance, provides direct unambiguous experimental measurements. The JPL-engine was designed specifically for the study of Stirling cycle performances and measured indicator diagrams are compared with computed results. The results show differences between the types of analyses, and indicate that at higher frequencies the dynamic effects included in the third-order codes become significant.
