Abstract: In the present study our intention is to dispatch the turbulent mixed convective flow and radiative flow in a vertical rectangular channel. The channel is constructed with two openings inlet and outlet. The turbulence is modelled by computational fluid dynamics (CFD) approach using lambremhorst turbulence model. Radiation is modelled with Discrete ordinates method (DOM). Finite difference method (FDM) is utilized to discretize the governing equations and an inhouse Fotron code is used to simulate the turbulent flow. The invariant study is carried out for the effect of flow opposite to buoyancy force and flow in same direction as buoyancy flow heat transfer characteristics. The heat transfer rate is remarkably altered by the flow opposite to buoyancy force and flow in same direction as buoyancy flow behavior observed inside the enclosure.
Keywords: lambremhorst Turbulence, Assisting flow, Opposing flow, discrete ordinates method.
