Videos of ST-XX Stirling engine test

In this the video you can see a test setup we prepared for evaluation of ST500 engine performance   

During the test we tried to keep all boundary conditions of the engine near to specific values as follows 

Coolant liquid flow (lit/min): 6.1

Coolant entrance temp. (‘C) : 33.5

Coolant exit temp. (‘C): 41.0

Heater tip temp. (‘C): 393

Heater base temp. (‘C): 353

By setting charge pressure of 8bar (Helium 99.98%) we obtained 440W of net output power. The software also predicted 405W which has about 10 percent error
