Inlet BCs of pressure and velocity for compressible multiphase flow
 

Hi.

I'm now working on the fuel injection problem and trying to simulate how the injector works during the fuel's atomization process.
I want to simulate the flow which inlet flow velocity and pressure are known, but I can't figure out how should I write the boundary conditions.
In some cases I saw, either velocity or pressure were set as fixedValue at inlet.

Does anyone could suggest me the solution for this problem?

The BCs I tried is totalPressure for pressure inlet, and flowRateInletVelocity for velocity inlet. The application is compressibleInterFoam. OpenFOAM version is 7.

Thank you.
