[TOC]
The condition sets the static pressure at the patch \( p_p \) based on a specification of the total pressure, \( p_0 \), and pressure drop, \( p_d \), specified as a function of the volumetric flow rate.
\[ p_p = p_0 - p_d \]
Field file entries:
<patchName> { type fanPressure; file "fanCurve"; outOfBounds clamp; direction in; // in | out p0 uniform 0; value uniform 0; // Optional entries U U; phi phi; }
The pressure drop is prescribed as a Foam::interpolationTable in the file given by the file
entry, taking the form:
( (vfr_1 dp_1) (vfr_2 dp_2) ... (vfr_n dp_n) );
