Abstract
On a point that heat transfer on cylinder walls is important to improve thermal efficiency of Stirling engines, flow and heat transfer simulation was performed using a commercial CFD software. It is done for the expansion space of a beta-type engine for a working gas of air at nearly atmospheric pressure with combination with one-dimensional multicomponent analysis. Heat flux on the walls are picked up and total heat flow was obtained. Change in heat flow from CFD has the same tendency as that from 1-D analysis except that low heat addition in the cooling process and heat removal in the compression process. The results are not deterministic because some strange tendencies exist.
