Detailed Description

This boundary condition provides a convective heat transfer coefficient condition.

if Re > 500000

\‍[ htc_p = \frac{0.664 Re^{0.5} Pr^{0.333} \kappa_p}{L} \‍]

else

\‍[ htc_p = \frac{0.037 Re^{0.8} Pr^{0.333} \kappa_p}{L} \‍]

where

$ htc_p $=patch convective heat transfer coefficient
$ Re $=Reynolds number
$ Pr $=Prandtl number
$ \kappa_p $=thermal conductivity
$ L $=length scale
Usage
