what exactly is fluid bulk temp in steady state convection?

sri mad Apr 14, 2011 2:02 PM

i want to know whether fluid bulk temperature in convection analysis is surface temperature or fluid temperature surrounding it.

i am trying to specify a fluid bulk temp of 300k with a convection coeff 100 w/m2k on a surafce and i want to whether solidworks is keeping the surface

as const with 300k or it is taking 300k as fluid temp surrounding it.

Bulk fluid temperature is the temperature far away from the hot surface, usually denoted T∞. Heat moves by difference in temperature from hot to cold, so the convective heat transfer equation includes (Ts - T∞), where Ts is the hot surface temperature.
