Abstract

Computational Fluid Dynamic (CFD) is major stride to handle turbulent problem in vital design industrial product enquiries and initiated process as an alternative of experimentally investigations for the dynamic fluid behavior. Assessment of turbulence models in many experiences reported come up with difficulties predicting near wall turbulence including the driven flow or the boundary interactions. This will provide strong motivation to emphasize the importance of boundaries further and to treat near the wall in mathematical fluid mechanics. This study is to understand and to improve wall functions (Robin-type) implementation for turbulence modeling. Channel flow was included as the test case of turbulent flow model. To accomplish this study, we used the finite difference method and computational code to simulate the channel flow model. Boundary layer simulation of fully developed turbulent channel flow which are using Low & High Reynolds numbers, Ret =395 up to 3950 respectively reported.
