Is it possible to obtain convective heat transfer coefficient in ANSYS FLUENT in a thermal analysis of Heat sink under natural convection in a room? And how?
I did a thermal analysis of a fin
input conditions were
ambient temp 30.c
heat flux 230w/m2K
and input velocity =0.0001m/s
note: I didnt enter convective heat transfer coefficient.
In results temp contours were fine
but surface heat transfer coefficient was 7.0e+17
which is absurd!
