I modelled a air cooled heat exchanger as porous media. Also I want to add heat transfer using radiator model in b.c(There is air flow in the porous zone). When I define the porous media, fluent automatically creat a interior-porous in internal boundary conditions and I defined this interior-porous as a radiator, but after run the calculation there wasnt any heat exchange.
Thanks in advance
Have a nice days.June 14, 2021 at 12:53 pmRobAnsys EmployeeWhat did you set on that surface? Images will help.

June 14, 2021 at 3:41 pmJune 14, 2021 at 3:46 pmJune 15, 2021 at 2:10 pmnisaniSubscriberI'm so sorry, I'm in a bit of a hurry. I thought you forgot to reply and created a new post.
June 15, 2021 at 2:11 pmnisaniSubscriberDo you have a any idea why its not working ?
June 15, 2021 at 4:08 pmRobAnsys EmployeeMore likely you posted after I finished for the day.
The jump in cell size won't help, but given the distance and dT you may find the contact time is too low. Plot the temperature contour with node values off on the same view as the velocity vector image.
June 15, 2021 at 4:35 pmJune 16, 2021 at 4:31 pmRobAnsys EmployeeYou're not setting the cell value, you're setting the model temperature. If you look at a household radiator it's generally a lot warmer than the air next to it.

June 17, 2021 at 11:11 amRobAnsys EmployeeI think it is working, increase the radiator temperature to 1500K and see what happens.
