Detailed Description

This boundary condition provides a gradient condition for internal energy, where the gradient is calculated using:

\[ \nabla(e_p) = \nabla_\perp C_p(p, T) + \frac{e_p - e_c}{\Delta} \]

where

\( e_p \)	=	energy at patch faces [J]
\( e_c \)	=	energy at patch internal cells [J]
\( p \)	=	pressure [bar]
\( T \)	=	temperature [K]
\( C_p \)	=	specific heat [J/kg/K]
\( \Delta \)	=	distance between patch face and internal cell centres [m]

Usage

Example of the boundary condition specification:

<patchName>
{
    type            gradientEnergy;
    gradient        uniform 10;
}
