Hi everyone how do you account the weight of turbine in flow simulation.
Basic setup for this type of problem:
Add local rotation
Finding out what velocity it will rotate the turbine by applying a mass flow for the inlet flow and then iterate the flow until it will have a zero torque On the blades.
(I try to change the materials of the turbine so that the weight will change, basically if the turbine has a higher weight then the fluid should have a higher velocity to turn the turbine but based on my study weight does not affect the result, even if you do not assign materials to the turbine the calculation will still completed and give you a value. )
