Abstract

Regenerative cycles have higher thermal efficiency than other closed cycles because of their heat recovery capability. In this manner, Stirling engines have advantage because regeneration can be applied easily to the cycle. In this study, effects of the regenerator on engine performance of a beta type Stirling were examined. Stainless steel wire, having 0.15 mm diameter and 15% solidity ratio, were used as regenerator material. Experiments were carried out at 800 degrees C hot end temperature and the charge pressures for 3, 4, 5, 6 bar. Maximum power and torque of the engine were measured as 1831.09 W at 1035 rpm, and 19.74 Nm at 837 rpm for engine without regenerator while as 1940.45 W at 1046 rpm, and 20.55 Nm at 867 rpm for engine with regenerator, respectively. It was found that the use of regenerator, the engine power and engine torque increased by 5.97% and 4% respectively.
