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

Example of the boundary condition specification:

    myPatch
    {
        type            convectiveHeatTransfer;
        L               0.1;
    }
