Detailed Description

This boundary condition can be applied to assign either a pressure inlet or outlet total pressure condition for a fan.

The switch nonDimensional can be used for a non-dimensional table. It needs inputs rpm and dm of the fan.

The nonDimensional flux for the table is calculate as :

phi = 4.0*mDot/(rho*sqr(PI)*dm^3*omega) where: dm is the mean diameter. omega is rad/sec.

The nonDimensinal pressure :

Psi = 2 deltaP/(rho*(sqr(PI*omega*dm))) where: deltaP is the pressure drop

The non-dimensional table should be given as Psi = F(phi).

Usage
Property Description Required Default value
file fan curve file name yes
outOfBounds out of bounds handling yes
direction direction of flow through fan [in/out] yes
p0 environmental total pressure yes
nonDimensional uses non-dimensional table no false
rpm fan rpm for non-dimensional table no 0.0
dm mean diameter for non-dimensional table no 0.0

Example of the boundary condition specification:

    inlet
    {
        type            fanPressure;
        file            "fanCurve";
        outOfBounds     clamp;
        direction       in;
        p0              uniform 0;
        value           uniform 0;
    }

    outlet
    {
        type            fanPressure;
        file            "fanCurve";
        outOfBounds     clamp;
        direction       out;
        p0              uniform 0;
        value           uniform 0;
    }
