Default Inlet BCs of pressure and velocity for compressible multiphase flow

kt.taro is on a distinguished road

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.
