Finite element solutions of a two-equation model of turbulent flow using a pseudo-time dependent approach
Abstract
A numerical method is developed to obtain the finite element solutions of the k-epsilon model of turbulent flow. The pseudotime-dependent method is employed to avoid the instability of the solution. Vorticity and stream-function formulation and the complete partitioning technique are also employed to save computer memories and computer time. A solution for the fully developed channel flow is obtained for the Reynolds number of 55,000. Solutions for the developing channel flows are also obtained for the Reynolds number of 55,000 and 2500.
