Combined effect of radiation and natural convection in a rectangular enclosure discreetly heated from one side

摘要: Purpose – The aim of this work consists studying numerically the coupling between natural convection and radiation in a tall rectangular cavity by examining effect emissivity walls, e, Rayleigh number, Ra, inclination cavity, θ, on flow characteristics existence ranges multiple solutions obtained.Design/methodology/approach Navier‐Stokes equations were discretized using finite difference technique. vorticity energy solved alternating direction implicit method. Values stream function obtained point successive over‐relaxation calculation radiative heat exchange walls is based radiosity method.Findings For an inclined (θ=45°), up to four different are their range found be strongly dependent number walls. In case vertical cavity...
