Heat Transfer Coefficient
Heat transfer coefficient, abbreviated as h, also known as film coefficient or film effectiveness, is the convective heat transfer between a solid surface and the fluid around it.
Heat Transfer Coefficient formulas
\(\large{ h = \frac { Q" }{\Delta T} }\) | |
\(\large{ h=\frac{ Nu \; k }{ l_c } }\) | (Nusselt number) |
Where:
\(\large{ h }\) = heat transfer coefficient
\(\large{ l_c }\) = characteristic length
\(\large{ Q" }\) = heat flux
\(\large{ Nu }\) = Nusselt number
\(\large{ \Delta T }\) = temperature differential between the solid surface and surrounding area
\(\large{ k }\) = thermal conductivity
