Validation of Wall Element Technique of Turbulent Flow

Abstract

An investigation based a finite element method (FEM) is carried out for the determination of confined turbulent flow with a one equation model used to depict the turbulent viscosity in a long straight channel. The effects of such flow in a zone close to a solid boundary has been investigated, by developing a finite element modeling technique based on near wall zone in which replaces the traditional techniques. The validity of the imposed technique is shown by comparison with other techniques.
