Numerical modeling of mixed convection heat transfer of laminar fluid in rectangular enclosure with openings in the side

Abstract EN

All analysis of mixed convection heat transfer inside a rectangular enclosure with side openings was numerically examined, ^lie fluid enters the enclosure through an opening in the vertical wall and exits home another opening placed in the light vertical wall.

Two-dimensional Navier-Stockes equations are solved by using control volume based finite element teclinique.

For mixed convection, the significant parameters Graf of number, Richardson number, and Reynolds number by which different fluid and heat transfer characteristics inside the enclosure reamlines, is Athens, average Nusselt number, maximum temperature other pai ameters of the heated wall aie reported in the present study for Ri = 0 to 10,Re = 50, 100, 500, 1000, Pr = 0.7 to 100 and different aspect ratios, the computational results indicate that the heat transfer coefficient is strongly affected by Reynolds number and Richardson number.

Higher Nussle number is observed at large value of Pr.

comparison of the present results leas been made air found in good agreement with known results.
