i try to determine convective thermal resistance (R[sub]conv[/sub]) at different diameters of channels in Steady State Thermal ANSYS , but did not work so far.
because if i define the channel as 3rd boundary condition (convection), i have to define the temperature and heat transfer coefficient h, what i actually do is that i indirectly determine convective thermal resistance, which is wrong.
With CFX I have already worked, I have varied the diameter and got different h and convective thermal resistance (R[sub]conv[/sub]).
Are there any suggestions on how to determine convective thermal resistance (R[sub]conv[/sub]) by varying the diameter in Steady State Thermal ANSYS?
Thank you
