The physical model considered here is a lid-driven porous square cavity with internal elliptic shape adiabatic block and linearly heated side walls. The top moving wall is well cold and set with uniform velocity. The bottom moving wall heated, linearly heated side walls and inside the elliptic shape adiabatic. The relevant parameters in the present study are Darcy number Da = 10-5-10-3, Grashof number Gr = 10³-105, Reynolds number Re = 1-10² and Prandtl number Pr = 0.7. The isotherms are also almost symmetric at small Re with higher Gr (Gr = 105) and Da (Da = 10-3) and natural convection is found to be dominant whereas the isotherms are compressed near the left and bottom walls at higher Re for linearly heated side walls. The solution of these governing equations is obtained numerically with the finite element approach using the Galerkin method of weighted residuals. Results are presented in the form of streamlines, isotherms, Local Nusselt number, average Nusselt number, velocity and temperature for the afore mentioned parameters. The numerical results indicate the strong influence of the mentioned parameters on the flow structure and heat transfer as well as average Nusselt number. An optimum combination of the governing parameters would result in higher heat transfer. [ABSTRACT FROM AUTHOR] |
