Detailed Description

This boundary condition provides a pressure jump condition, using the cyclic condition as a base.

The jump is specified as a Function1 type, to enable the use of, e.g. constant, polynomial, table values. This boundary condition can operate in two modes - standard and backward compatibility. In standard mode, jump is specified as a function of total volumetric flow rate through the patch. In backward compatibility mode, the boundary conditions serves as a direct replacement for the fanFvPatchField, where jump is defined as a function of local velocity.

Usage
Property Description Required Default value
patchType underlying patch type (should be cyclic) yes
fanCurve fan curve function yes
jumpTable jump table function (backward compatibility mode) no
reverse reverse jump direction no false
phi flux field name no phi
rho density field name no rho

Example of the boundary condition specification: 

    <patchName>
    {
        type            fanPressureJump;
        patchType       cyclic;
        fanCurve        table;
        fanCurveCoeffs
        {
            file            "$FOAM_CASE/constant/pressureVsQ";
            format          csv;
            nHeaderLine     1;
            refColumn       0;
            componentColumns 1(1);
            separator       ",";
            mergeSeparators no;
            outOfBounds     clamp;
            interpolationScheme linear;
        }
        value           uniform 0;
    }

The above example shows the use of a comma separated (CSV) file to specify the jump condition.

Note
The underlying patchType should be set to cyclic
