ctually i'm working on CFD simulation the flow inside a kind of small axial hydraulic turbine (for research non profit purpose) where can i find benchmark case (that give full flow information) to validate my results, because to this time i can only find performances curves (power, torque, flow rate, rpm) are they enough

I appreciate if someone has any data that can be used to validate a simulation of a small axial hydraulic turbine.

Many thanks

is there any NACA examples for incompressible flow

Here is validation data for NACA 0012.

I have a model of that in ANSYS 17.2 that I can send you if you want it. Just reply with your email. The model doesn't exactly recreate the model described in the validation data above because it was built for an edX course I was taking and had to fit within the limitations of the student license.

Since you have performance curves for flow rate for example, why don't you compute the flow rate in your CFD model and see how close it comes to the same point on the performance curve?  If the flow rate is plotted against rpm, then you can run your CFD model at multiple rpm values and plot multiple points on the published performance curve.

Brilliant ! thanks Peter
