Abstract
The finite element solution of turbulent flows using a (k-epsilon) tur bulence model usually presents severe numerical difficulties. Develops an iterative (k-L)-predictor/epsilon-corrector algorithm for overcomi ng this and solving the (k-epsilon) turbulent models. The iterative sc heme achieves convergence in L (length , scale) which is proportional to (k(1.5)/epsilon). Numerical results indicate that the developed ite rative algorithm is very robust.
