Hi,all:
As in Eugene's PhD thesis, the parabolic profile is modified by here, as in the reference paper"Coherent structure dynamics in near-wall turbulence, Schoppa,1999", the profile's maximum streak is at y+=30, while in the perturbU code: Code:
U[celli][streamDir] += (utau * duplus/2.0) * (yplus/40.0) * Foam::exp(-sigma * Foam::sqr(yplus) + 0.5) * Foam::cos(betaPlus*zplus)*deviation; |
