i would like to know, how to specify the Blade profile using Theta specification option also how to determine the wrap angle for a blade. I would also like to know how changing the wrap angle would effect centrifugal compressor performance

Right click on the angle view (bottom left) and click "theta definition" to switch from defining beta to defining theta.

Hi there!

A bit off-topic, could you tell me how to determine the wrap angle. I have calculated the basic impeller dimensions, ie,
1. Meridional velocities at impeller inlet and exit
2. The diameter of the impeller at the inlet and exit
3. The diameter of the hub at the inlet
4. Inlet vane angle
5. Outlet vane angle
6. RPM and hence the peripheral velocities at the inlet and outlet

How do I calculate the wrap angle now?
I'm using BladeGen to generate the impeller but I cannot accurate do it unless I have this
