Detailed Description

This boundary condition is designed to be used in conjunction with surface film modelling. It provides a velocity inlet boundary condition for patches where the film height is specified. The inflow velocity is obtained from the flux with a direction normal to the patch faces using:

\[ U_p = \frac{n \phi}{\rho |Sf| \delta} \]

where

\( U_p \)	=	patch velocity [m/s]
\( n \)	=	patch normal vector
\( \phi \)	=	mass flux [kg/s]
\( \rho \)	=	density [kg/m3]
\( Sf \)	=	patch face area vectors [m2]
\( \delta \)	=	film height [m]

Usage

Property	Description	Required	Default value
`phi`	Flux field name	no	phi
`rho`	density field name	no	rho
`deltaf`	height field name	no	deltaf

Example of the boundary condition specification:

    <patchName>
    {
        type            filmHeightInletVelocity;
        phi             phi;
        rho             rho;
        deltaf          deltaf;
        value           uniform (0 0 0); // initial velocity / [m/s]
    }
