Constant pressure despite temperature changes?
I'm running a reacting foam case where I have edited the solver to ensure the density is constant. My problem is, I'm getting laminar flows (despite having an LES turbulence model turned on), which I can only attribute to the uniform pressure field in my results. The pressure field should not be uniform, as I have temperatures of up to 2000 in the flow.
As far as I can work out, this is in some way a result of my boundary conditions, yet no matter what combination I try I can't seem to solve it. I have a 3d cylindrical mesh with inlets on the sides and an outlet on the top. My inlets have a fixed velocity and zerogradient pressure, the outlet has zerogradient velocity and fixed pressure. I've tried various combinations of fixedfluxpressures and wavetransmissive BCs, yet still my pressure is perfectly uniform. Ideas?
