Different discharge port diameter but exactly same performance result #80

Closed Wang-Zongwei closed 1 year ago

Wang-Zongwei commented 1 year ago

I want to study with PDSim GUI the impact of different discharge port diameter on scroll compressor performance. But I found it seems no performance change (volumetric and isentropic efficiency) under different discharge port diameter input.

GUI version: PDSim 2.14 and CoolProp 6.5.0 All scroll input parameter keeps same as default setting value except discharge port diameter.

Do you think such result is reasonable? Thanks very much. Dis port

Are the coordinates of the port the same? You might want to put in the port coordinates yourself

Wang-Zongwei commented 1 year ago

I did't input any coordinates for the discharge port (all x,y keeps blank). I will try with different coordinates input data to see if the performance result is different.

Wang-Zongwei commented 1 year ago

I have got reasonable performance result with different coordinates input data for discharge port (see pic). I will use this method for my future study. xy

Thanks for your help. @ibell
