I have an impeller pump drawing and I want to know how to check stress on the fins. Can anyone help me? Thanks

To analyze the actual stress on the vanes of a pump impeller one of the things you need to know is the pressure contours on the surface of the the vanes, to do that you will need to create a model of the complete pump and run a CFD Analysis with Flow Simulation (COSMOS FlowWorks).  Also, you will need to consider centrifugal forces, etc.

Stress, deformation, fatigue analysis, etc. of pump impellers is not an easy job,  a centrifugal pump impeller is subject to many loads and forces and it is a rotodynamic hydromechanical component.

Hi Langgeng,

Find attached a similar case for the analysis of a gas turbine rotor, I wish it may help
