The engine speed and pressure dependences of performance of the laboratory research Stirling engine MELSE IIIs have been measured for six species of regenerator matrix ; five wire gauses with different mesh numbers and one smonge metal. In addition to the ordinary characteristics such as shaft power, indicated power and thermal input, the flow friction and reheat losses at the regenerator have been determined from the measurements of the instantaneous pressure changes and the heat removed by cooling water, respectively. These two losses related to regenerator matrix properties have been compared with the theoretical ones calculated from fundamental matrix data according to rather simple models. The results indicate that the optimum matrix and geometry of the regenerator can be obtained theoretically.
