Total Presure Ratio in Rotor 37

BalanceChen · June 19, 2011, 23:21

Hi all, I am simulating the flow in the Rotor 37 and compare the results to the experimental ones. But who can tell me how should I do the average, by mass flow average or area average, in order to be consistent with the experimental results.

Lots of thanks,

Use the same as the experimental results. What result are you comparing to and how was it calculated.

But i found no comments on how the experimental results averaged...

I take a test by using both area average and mass flow average to get the total pressure ratio, found the difference between is very little, about 0.01. So, there may be not a big problem here on which average method is used.
