I am doing a simulation through the duct of an aircraft compressor. Air comes in at higher temperature into the duct. Inside the domain, cooler air is injected through holes. So basically I am simulating flow with heat transfer.
Unfortunately I am getting an oscillatory residual behaviour which is non converged. As a result, the solution is absurd (like the mass flow is not conserved between the inlet, outlet and injection ports).
Can someone suggest what to do?
Please, it is urgent.
