Abstract

Two analytic models for a water-type Stirling engine were newly developed. One is the constant temperature model, assuming the constant temperatures of working fluid, and the other is the heat transfer model, considering with the heat transfer between the heat sources and the work fluid. The constant temperature model is a conventional model for analyses of a Stirling engine. However, in an actual Stirling engine the temperatures of working fluid are not perfectly fixed, and there is few literature on a water-type Stirling engine. Therefore, these analytic models were newly developed. Using these two analytic models, influences of the resonance pipe length and the heat transfer coefficient over the performance of the engine were investigated numerically, and the tendencies in optimum values of these parameters were shown.
