Non-uniform Unsteady Periodic Inlet Boundary Conditions in OpenFOAM

hakolekar · November 19, 2018, 20:44

Hi,

I am trying to simulate a turbine blade with unsteady incoming wakes in OpenFOAM.

For the same, I want to use non-uniform inlet profiles of totalPressure, totalTemperature, pressureDirectedInletVelocity, fixedValue TKE and fixedValue omega, which are from high-fidelity simulations and are representative of a wake downstream of a turbine blade. Using these profiles saves computation time.

These profiles should however be able to move in the pitchwise direction with a user defined velocity and they should also be periodic in the pitchwise direction.

Can anyone please provide suggestions on how to get started with this problem.

Attached is a simple sketch

Thank you.
Regards,
Harshal
