Hey, iam Simulation the flow in an axial turbine. The flow comes from the rotational detonation combustion, where 2 shockwaves travels around the annulus in the turbine. I just simulate 15 stator blades without rotor blades, so there is no rotation speed. At the Inlet of my domain for my unsteady Simulation I have the unsteady inlet boundary conditions where the total pressure and total temperature are functions of the time and the azimuthal angle. So in FINE/Open-Tutorial *OpenLabs Tutorial 2: Customized Unsteady Inlet Boundary Condition* in the FINE/Open-manual is the following equation.
