Default Why Fluent Solver Wrong?
Posts: n/a
Dear CFD Users

I would like to ask one of the CFD, FLUENT solver problem which I faced in my project.

I am solving a problem with two gas mixing in 3-D, the 1st gas is mixing in 2nd gas by fraction of amount with time through small opening. The Boundry is fully closed.

Problem: suppose, I consider the 1st gas pressure higher that the 2nd gas preassure (P1>P2) and T1<T2 in these conditions the solver is showing unrealistic variation in pressure and T1>T2, the results are realistic and convergency. Why this situation is happening in FLUENT solver? can you advise me, how to overcome this problem.

your suggestions are appereciate in advance
