Hi to all!
I tried to simulate axial compressor, but got confusing results for static pressure and temperature.
I used total pressure and total temperature at inlet and corrected massflow at exit. Here one can see my results for 4 corrected massflow values: 12.5, 13, 15 and 20 kg/s for the whole machine.
Point №17 (out) means the last stage exit, point №16 (R7) is for the cross-section between rotor wheel and stator wheel in the seventh (last) stage
As I know, the pressure should increase even in the last stator wheel domain, but it tends to decrease and just drop down for higher massflow values.
What is the reason of it? The most curious for me is the case with corrected massflow value about 34 kg/s (about 54 kg/s for non-corrected massflow), but I'm miles away from desired point yet...

Thanks in advance...
