Detailed Description

template<class Type>
class Foam::porousBafflePressureFvPatchField< Type >

This boundary condition provides a porous baffle pressure jump condition, using the cyclic condition as a base. The jump in pressure is defined by:

\[ \Delta p = -(D \mu U + 0.5 I \rho |U|^2 )L \]

where

$ p $ = pressure [Pa]
$ \rho $ = density [kg/m^3]
$ \mu $ = laminar viscosity [Pa s]
$ D $ = Darcy coefficient
$ I $ = inertial coefficient
$ L $ = porous media length in the flow direction
Usage
Property Description Required Default value
patchType underlying patch type (should be cyclic) yes
phi flux field name no phi
rho density field name no rho
D Darcy coefficient yes
I inertial coefficient yes
length porous media length in the flow direction yes
relaxation relaxation factor for pressure jump no 1

Example of the boundary condition specification: 

    <patchName>
    {
        type            porousBafflePressure;
        patchType       cyclic;
        jump            uniform 0;
        D               0.001;
        I               1000000;
        length          0.1;
        relaxation      0.2;
        value           uniform 0;
    }
