Hey Fabian

Thanks for your reply.

These suggestions are really good. But the problem was rather simple and has been solved. The increase in the velocity near the outlet was because velocity...

Hey

I modified the simpleFoam solver and added T equation in it. It is also showing me the same problem as it was with buoyantBoussinesqSimpleFoam. The velocity is increasing from inlet to outlet....

I changed the p_rgh to buoyantPressure and p file to zeroGradient at the inlet and fixedValue at the outlet.

It is showing this error

Hey Tushar

I tried that also, but it didnt work. Another thing is that its totally forced convection and my gravity is also zero so buoyant does not mean anything here as I have understood. I do...

Hey

I think I got the perturbation pressure, is it the pressure correction term in the SIMPLE algorithm?

Here is the solver


00002 volScalarField rUA("rUA", 1.0/UEqn().A());

Hey Deji

Thanks for the reply..

I am using zeroGradient at the inlet and fixedvalue (uniform 0) at the outlet. I am sorry but I dont know the meaning of perturbation pressure.

Hey Tushar

Good to see your reply again..

No I am using my own solver. Sorry for the language. It meant when I shifted from simpleFoam to buoyantBoussinesqSimpleFoam. It seems to be a bit easy...

Hey Deji

I do not understand your reply. I have taken zero gravity so do you still think It will work?
secondly I tried it but it is diverging.
Now pressure is also converging but the velocity...

The problem remains same with correct calculations also. I am attaching more files now. The velocity is going beyond its correct value.

I found the solution to my earlier problem, Now the problem is different and the velocity which is 1 m/s at the inlet is going above to 1.14 m/s at the outlet. I am posting the case files and...

Hey

I just checked my results. The velocity vectors are showing that the velocity reaches to zero value near the outlet. It is non physical as velocity should be 1 m/s everywhere.

forced convection of air inside a heated rectangular channel

Hey,

I am simulating the forced convection of air inside a heated rectangular channel. The air velocity is 1 m/s at the inlet. The temperature of the all four walls is 400 K and air is at 300 K....
