Hello everyone, <\/p>\n

I am modelling flow through C-D nozzle in 3D. For this I have 2 Fluid Domains and 1 Solid Domain. 1 Fluid domain is used to produce supersonic flow and the other fluid domain has coolant in it which cools down the solid present in between the fluids. I am having confusion with specifying the wall thermal conditions as I want to see how much coolant can cool down the solid walls. For this I am using mass flow rate inlets and pressure outlets. Both flows are counter flow. For now i am giving solid walls, as following. The problem i am facing is that proper heat transfer is observed and proper temperature contours are not developed . Kindly help me out to define the wall thermal conditions properly.<\/p>\n
