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
Property Description Required Default value

Example of the boundary condition specification: 

    <patchName>
    {
        type            convectiveHeatTransfer;
        L               0.1;
    }
