Openfoam nutilda boundary
WebNote. The boundary condition is derived from inletOutlet condition. Therefore, in the event of reverse flow, a zero-gradient condition is applied. The order of precedence to input the empirical model constant Cmu is: turbulence model, boundary condition dictionary, and default value=0.09.; The empirical model constant Cmu is not a spatiotemporal variant field. WebThe nutUSpaldingWallFunction boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, based on velocity, i.e. U for low- and high-Reynolds number …
