CFD-Post Turbo: Gas Compressor Performance Macro
Hi all,
I used gas compressor performance macro and i got a lot of variables. These are inbuilt macros. Is there some documentation of these macros where i can learn how these have been obtained? I am unable to figure out the meaning of these terms. Please help me out. |
Which variables are you having trouble with? I can probably help you define them.

These are the expressions : (Mainly efficiency variables)
effPTS = ((gamma-1)/gamma)*log10(pOut/pTotalIn)/log10(tTotalOut/tTotalIn) effPTT = ((gamma-1)/gamma)*log10(pTotalOut/pTotalIn)/log10(tTotalOut/tTotalIn) effTS = (1-(pOut/pTotalIn)^((gamma-1)/gamma))/(1-tTotalOut/tTotalIn) effTT = (1-(pTotalOut/pTotalIn)^((gamma-1)/gamma))/(1-tTotalOut/tTotalIn) --------------------------------------------------------------------------------------- It would be great if you could point me to some manual where all these are defined. I couldn't find the exact definitions of these. |
"P" stands for the polytropic efficiency, while no "P" is the isentropic.
"TT" means the total-to-total. |
