WebThe importance of CFD tools is their capability of computing wall heat flux in unsteady thermal boundary conditions where wall temperature is continuously varying during the time. On the other hand, Semi-empirical methods estimate heat flux based on Nusselt number which would be rather constant when wall temperature tends to change. WebThis boundary condition describes an inlet vector boundary condition in cylindrical coordinates given a central axis, central point, rpm, axial and radial velocity. …
