Forced Convection over a plane plate
Hi guys, I calculated the cooling of a plate by a turbulent forced convection analytically. Now I want to check my results with COMSOL but I have some troubles, maybe someone would be so kind and help...

Hi, I just simplified my structure to test the stuff with a constant temperature of +4°C. It's really strange because I get a maximum temperature of -12°C, so not even my boundary with my constant...

Hi, I just checked it with an older version of COMSOL (3.5). When I set there a constant temperature at a boundary this temperature also appears in the result (direct on the boundary, of course ;-)...

Hi, I tested your model and noticed same problem. This has maybe something to do how Comsol handles wall functions. I don't know is this right or wrong but if you want to get rid of this use "...

@ Tero: it works with Low-Reynolds k-epsilon. But when i investigate my real problem with a boundary heat source my results are a little bit strange. @ all: To be sure I can use the turbulent model I...

Hi Matthias, You have used Turbulent flow and Heat transfer by separated physic. Instead of this, use Isothermal Flow where turbulent flow and heat transfer are connect with each other. Also check what...

Hi Tero, thank you for the link. I already read it but i jumped over the last paragraph. Thank you very much!!!!!! Can someone tell me what the "dimensionless distance to cell center" is, and how is it...

Hi guys, I'm still searching for a definition of the dimensionless distance to cell center. Can someone tell me how it is calculated!?!?!? thx
