# 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 formula

\(\large{ h = \frac { Q" }{\Delta T} }\)

Where:

\(\large{ h }\) = heat transfer coefficient

\(\large{ Q" }\) = heat flux

\(\large{ \Delta T }\) = temperature differential between the solid surface and surrounding area
