Abstract
An extended k-epsilon model that includes the low Reynolds number region has been implemented into a finite element based Reynolds averaged Navier-Stokes solver. Three-dimensional turbulent flows can be calculated either with wall functions that are valid in the whole wall region or with computation up to the wall. Severe iterative convergence problems ar encountered when using the Newton-Raphson method; however, the use of time-marching algorithms is more encouraging. Numerical results for two-dimensional turbulent channel flows have been obtained without any use of complex relaxation procedures and show good agreement with experiments.
