Hello <\/p>\n
<\/p>\n
I have been trying to do a non thermal equilibrium simulation in fluent. My domain is just a 2d section of a pipe (a rectangular domain with 3 inches length* 0.5 inches height and I also added an entry and exit sections (one rectangle at inlet and other rectangle at outlet) as well just so the flow is fully developed. My boundary conditions are also simple : constant temperature at wall (top and bottom of rectangle) , velocity inlet and pressure outlet. For the poros zone which is the entire pipe section (center rectangle) I gave the porosity, permeability, form coefficient, heat transfer coefficient. <\/p>\n
<\/p>\n
So I tried using viscous laminar model first and then the viscous k-epsilon turbulence models just to see how they behave (my velocity is 23 m\/s which is high for laminar but still should show some difference in temperature profiles right??). But when I plot the temperature profiles at the outlet, I see little to no difference at all in both the temperature profiles. I am attaching these temperature profiles in the attachment, (on X axis is the Y direction and Y axis is temperature), please have a look. <\/p>\n
<\/p>\n
Also I tried doing the same simulation with the same domain (rectangular with inlet and exit sections) without poros zone and when I use laminar and turbulence models at same velocity 23 m\/s, the temperature profiles are as they were supposed to be for a p![\"\"](\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/09\/28-09-2023-1695941169-IMG-20230928-WA0006.jpg\")
