You have the wall set at a constant temperature by your boundary conditions (Heat Source\VS Temperature 1), so by definition the wall will always be at this temperature and you may as well not even blow any air on it.
If your goal is to find the equilibrium temperature of the wall, then remove the heat source on the wall. You can set the initial temperature from the project settings (default setting is 20C for all solids and fluids I believe.)
By the way, this model is just the wall just floating in air. Is this really how you want to simulate it? You will have heat transfer to the wall on all sides as the air from the nozzle is blow on and around the wall.
Thank you for testing my modell.
I' m not intresting in the temperature off the wall att all.
Just the heat transfer coefficient (how effective different nozzels design).
If you check the xy Plot 1 you should get this result se picture. but it should be higer like 300 [W/m^2/K]
In teoret and practical tests.
It seems that Solidworkt calculate the heat transfer coefficient from wall to air and not the opposit that i want see. formula.
