Hello,
Could someone provide any reference for the computation of the poiseuillePressure in the poiseuille flow showcase:
[code=“cpp”]
/// Linearly decreasing pressure profile
T poiseuillePressure(plint iX, IncomprFlowParam const& parameters) {
T Lx = parameters.getNx()-1;
T Ly = parameters.getNy()-1;
return 8.*parameters.getLatticeNu()parameters.getLatticeU() / (LyLy) * (Lx/(T)2-(T)iX);
}
Many thanks in advance!
