FARKLI ÇALIŞMA GAZLARININ STIRLING MOTORUNUN PERFORMANSINA ETKİLERİNİN DENEYSEL OLARAK İNCELENMESİ

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.
