Springroove New Member Xilef Smith Join Date: Apr 2017 Posts: 19 Rep Power: 9	Dear, I am running simulations in a low Reynolds number environment (~ order of 10^5) When I analyse the pressure coefficient distribution, I see that that it reaches a maximum of 7(!). Is this even possible? I know that for supersonic flows, the coefficient can be slightly larger than one, but not to these magnitudes as far as I know of. The free stream Mach number is only 0.88 and reaches 2.2 locally. Is there maybe something wrong with the Cp interpretation? Cheers! Last edited by Springroove; January 30, 2018 at 08:12.
