Nümerical modelling of forced convection heat transfer in an open cavity

In this study, combined forced and natural convection heat transfer and fluid flow are examined in an open cavity. The effect of cavity geometries like cavity depth, cavity length, on heat transfer rate is investigated. As a flow parameter, Reynolds number, heat flux, heated wall position and Richardson number effect of the heat transfer are investigated. The cavity left wall is heated with constant heat flux, while other walls are kept at the adiabatic condition. The working fluid is assumed as air with Pr=0.71. For numerical analysis FLUENT Software is used in order to solve incompressible, two-dimensional, steady-state flow. For momentum and energy equations second-order upwind scheme is used. Length to depth ratio and height to depth ratio of the cavity is varied between 0.25Keyword: Isı geçişi = Heat transfer ; Zorlanmış taşınım = Forced convection
