Free Piston Stirling Engines - Some Model Tests and Simulations

Abstract

<div class="htmlview paragraph">Model tests of several 0.1 hp free piston Stirling cycle engines were made. They showed good piston displacer phasing and thermal efficiency in the 10% range. An instructive isothermal computer simulation was developed which compared reasonably well with model data and allowed investigation of parameter changes. Some possible configurations, power transfer, and control methods were considered.</div>
