Farklı çalışma gazlarının stirling motorunun performansına etkilerinin deneysel olarak incelenmesi

Bu çalışmada, gama tipi bir Stirling motorunda çalışma gazı olarak hava, argon ve helyum kullanılarak performans testleri yapılmıştır. Motor, 700, 800, 900 ve 1000 °C ısıtıcı sıcaklıklarında ve 1, 1,5, 2, 2,5, 3, 3,5, 4 ve 4,5 bar şarj basınçlarında test edilmiştir. Deneylerde motor gücünün şarj basıncı, motor devri, ısıtıcı sıcaklığı ve çalışma gazına bağlı olarak değişimleri incelenmiştir. Motorda maksimum çıkış gücü helyum gazı kullanılarak, 4 bar şarj basıncında ve 1000 °C ısıtıcı sıcaklığında 893 d/d motor devrinde, 128 W olarak elde edilmiştir.

An experimental investigation of the effects of various working fluids on stirling engine performance

In this study, performance tests of a gamma type Stirling engine were conducted using air, argon and helium as the working fluid. The engine was tested between 700-1000 °C hot source temperatures with 100 °C increments and 1-4.5 bar charge pressures with 0.5 bar increments. Tests were intended to determine the variation of engine power with charge pressure, engine speed and hot source temperature for each kind of working fluid. The maximum power output of the engine was obtained as 128 W with helium at 4 bar charge pressure, 1000 °C hot source temperature and 893 rpm engine speed.
