Hey everybody,
currently im working on my Bachelor-these which is a CFD Simulation of an oven with a constant flow in and out.
One step is to look at the influence of the natural convection of the flow field. The reynolds number inside is pretty low without the convection (Re= 60)
The temperature between the flow at the Inlet and the heated wall is very high. (1000 K)
Now for the natural convection i need to set a density model.
I read a lot about the ideal gas, the incompressible ideal gas and the boussinesq model but nothing specific to my case and which one fits the best.
I guess the boussinesq is wrong because of the high difference in temperature. And because the of that i guess that the pressure difference inside the oven will be to significant to just use the incompressible model...
Can anybody correct me or got a solution for this problem?!
