Hallo I am
having problem calculating the heat transfer from Walls to a Fluid (Water) correctly.
My first question is. What exactly is Turbulent thermal Diffusivity [kg/(s m)] in the
Start parameters. I know that I should know this but even extensive googling
My second and last question is what the temperature value in the boundary condition
turbulent heat flux is used for?
The information I have about my problem are:
Geometrical shape of the floe regime.
Type of Fluid.
Flow speed. Inlet Temperature. Heat flux across one wall.
In my opinion that should be enough to calculate the temperatures of the wall in my low turbulence case.
Thanks for your suggestions.
