Progress of Solution Methods Based Boundary Layers of Turbulent Flow

Abstract: In the present work, an effective technique with significant grid refinement has been developed and adopted to model the variation of the pertinent variables near a solid boundary using finite element method based solution for general steady-state two-dimensional, incompressible confined turbulent flow in long parallel-sided channels with a one-equation model to depict the viscosity of turbulence. Particular attention is given to the important aspect of studying the flow behaviour in the 'near wall zone’ of confined flow. Accurate model within the near wall zone is used to obtain correct overall predictions which resulted from the transfer of mass and momentum within this zone. As a result of this some innovative techniques regarding the mapping of the near wall zone were developed. In the present work different methods of solutions have been tested when the near wall zone has been extended away from the solid wall.
