Graph plot between Pressure ratio and constant span

sushil1151 · May 12, 2023, 09:38

Does anyone have an idea how to calculate the inlet and outlet pressure at constant span (Lets say at 0.2,0.4,0.6,0.8,1.0)?
If I am able to calculate the inlet and outlet pressure at given span then I will be able to calculate the pressure ratio and plot the graph between pressure ratio and normalized span. Please help me out.

Many ways to do this. For me, I prefer this way:
Insert two Plane at some axial position you like as inlet and outlet.

Locatio-ISO clip

select the plane you interted, select the virable "Radius", insert the uppon bound and the lower bound. For example, the hub is at R = 0.1 and the shroud is R = 0.2, so the 10% span is Radius>= 0.1 and Radius <= 0.11

It is more efficient to use CCL in command editor
