This boundary condition provides a fan pressure jump condition, using the cyclic condition as a base. The jump is specified as a Function1, which returns the pressure jump as a function of the total volumetric flow rate through the patch.

This boundary condition provides a fan pressure jump condition, using the cyclic condition as a base. The jump is specified as a Function1, which returns the pressure jump as a function of the total volumetric flow rate through the patch.
A backwards-compatibility option is also provided to specify the pressure jump as a function of local velocity. In this mode the boundary condition serves as a direct replacement for the old fanFvPatchField.
| 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 |
