Pressure outletPore scaleIn this work, new pressure inlet and outlet boundary conditions are developed for Smoothed Particle Hydrodynamics (SPH) that allow the natural development of in- and out-flow velocity profiles for any complex and irregular domain shapes and flow paths. The use of numerical...
For the Pressure Outlet BC: I set the gauge pressure to the gauge pressure of the of the inlet. But this shouldn't matter since it is all supersonic flow The problem is that fluent computes a velocity at the inlet that is at least too large by a factor of 2!
This velocity inlet boundary condition is applied to patches where the pressure is specified. The inflow velocity is obtained from the flux with a direction normal to the patch faces.More... Inheritance diagram for pressureInletVelocityFvPatchVectorField: ...
Pressure outlet is adopted as outlet BC of all channels and an identical relative pressure 0 MPa is given. The commonly used inlet conditions in FLUENT are pressure inlet and velocity inlet. Although the mass flow rate is known for the whole domain, it is impossible for the whole domain to...
Outlet pressure (both ports) will be something. If the mesh is OK, and that's both the cell quality and resolution this should solve nicely. You can then report the mass flow and velocity on the outlets. Why is the supersonic pressure 42MPa? Venting to atmospheric pressure? Set that...
edit: In fact due to phase oscillation I may always have backflow. I'm actually pretty certain that it doesn't affect fluent in terms of getting a bad simulation (other than false velocity vectors of backflow volume fraction) but I'm worried that it will affect convergenc...

Sonic velocity? Noise? Ask the vendor. Remember - More details = better answers Also: If you get a response it's polite to respond to it. GBTorpenhow (Mechanical) 18 Aug 23 18:03 This is something of a guess but I suspect it has to do with controllability. The capacities publish...
