| Summary: | The rise of concern on green and sustainable power production system has led to a rise
of interest among researchers in developing external combustion engines such as Stirling
engine. In this study, an up-scaled gamma-typed Stirling engine with the total swept volume
of 85cc., volume compression ratio of 1.5 with the use of mesh-wired heat regenerator has been
tested for its performance. The heat regenerator is mesh-wired, made of steel wool with the
diameter of 3.2cm and height of 1.5cm which is placed inside the working fluid flow passage
in between the displacer cylinder and the power piston cylinder. The working fluid used for the
engine operation is air, the heat source is Liquefied Petroleum Gas (LPG) and the cooling jacket
to stabilize the cold temperature is using water. Based on the experimental results, it shows that
at the heat input of 65J, the gamma engine was able to operate in self-pressurized mode at the
hot source temperature of 280C and cold temperature of 32C. The overall performance of the
engine using heat regenerator has improved over the performance of the engine without heat
regenerator. At no load test condition, the brake power from Beale formula has improved by
1%, brake thermal efficiency (BTE) has improved by 0.9% at the higher temperature difference
between hot source and cold temperature of 1% as compared to the engine performance without
heat regenerator |
