[Nitrox416]

Hello all,
I have to calculate the entropy generation following the Bejan relationship, i used the velocity gradients and temperature gradient which are available in cfd post from the cfx simulations, but once integrated on the entire volume I found the generation being only 6W over a total compressor power of 6000W.

Somebody has done this before and has some suggestion? I check expression, methodology and units more than one time and I can't sort out the problem

Thanks for help
