Stirling çevirimi ile çalışan beta tipi bir motorun imali ve performans testleri

Bu çalışmada, tek silindirli, 192 cm3 süpürme hacmine sahip, beta tipi bir Stirling motorunun imalatı ve performans testleri yapılmıştır. Deneyler 800, 900 ve 1000°C ısıtıcı sıcaklıklarında, 1, 1,5, 2, 2,5 ve 3 bar şarj basınçlarında yapılmıştır. Çalışma gazı olarak hava kullanılan deneylerde, motor devri, ısıtıcı sıcaklığı ve şarj basıncına bağlı olarak moment ve güç değişimleri elde edilmiştir. Deneylerde 1000°C ısıtıcı sıcaklığında 2,5 bar şarj basıncında 344 d/d motor devrinde, maksimum 14 W güç elde edilmiştir.

Manufacturing and testing of a $beta$-type stirling cycle engine

In this study, a single cylinder $beta$-type Stirling engine with the swept volume of 192 cc was manufactured and performance tests were conducted. Experiments were performed at 800, 900 and 1000°C heater temperatures and 1, 1.5, 2, 2.5 and 3 bar charge pressures. Air was used as the working fluid. Torque and power variations were obtained for different engine speeds, heater temperatures and charge pressures. Maximum output-power was obtained as 14 W at 344 rpm engine speed, at the heater temperature of 1000°C and 2.5 bar charge pressure.
