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]


Patch 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:

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