Detailed Description

Applies an explicit pressure gradient source in such a way to deflect the flow towards an specific direction (flowDir). Alternatively add an extra pressure drop in the flowDir direction using a model.

Usage

Minimal example by using constant/fvOptions:

directionalPressureGradientExplicitSource1
{
    // Mandatory entries (unmodifiable)
    type            directionalPressureGradientExplicitSource;

    // Mandatory entries (unmodifiable)
    model       <modelName>;
    fields      (<fieldName>);

    // Mandatory entries (runtime modifiable)
    flowDir     (1 1 0);
    faceZone    <faceZoneName>;

    // Conditional mandatory entries (unmodifiable)

        // when <timePath>/uniform/<name>Properties file exists
        gradient    <vectorField>; // reading from the aforementioned file

        // when model=DarcyForchheimer
        // deltaP = (D*mu + 0.5*rho*magUn)*magUn*length
        D           5e7;
        I           0;
        length      1e-3;

        // when model=constant
        pressureDrop    40;

        // when model=volumetricFlowRateTable
        outOfBounds     clamp;
        fileName        "volFlowRateTable";

    // Optional entries (runtime modifiable)
    relaxationFactor    0.3;

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: directionalPressureGradientExplicitSource	word	yes	-
`model`	Pressure drop model [Pa]	word	yes	-
`fields`	Name of operand field	word	yes	-
`gradient`	Initial pressure gradient field	vectorField	cndtnl	-
`flowDir`	Deflection flow direction	vector	yes	-
`faceZone`	Name of upstream faceZone	word	yes	-
`relaxationFactor`	Relaxation factor for flow deflection	scalar	no	0.3
`D`	Darcy pressure loss coefficient	scalar	cndtnl	-
`I`	Inertia pressure lost coefficient	scalar	cndtnl	-
`length`	Porous media length	scalar	cndtnl	-
`presssureDrop`	Constant pressure drop	scalar	cndtnl	-
`fileName`	Interpolation table for volumetric flow rate	interpolationTable	cndtnl	-

Options for the model entry:

      volumetricFlowRateTable | Pressure-gradient file
      constant                | Constant pressure drop
      DarcyForchheimer        | Darcy-Forchheimer model

The inherited entries are elaborated in:

Note

In order to obtain the upwind velocities this function loops over the slaves cells of the faceZone specified in the dictionary, on the other hand, the cellZone to which this source term is applied should be composed of the master cells and they should be 'downwind' the faceZone.
