Double-Diffusive of Natural Convection in an Inclined Porous Square Domain Generalized Model

Abstract

Numerical investigate of double-diffusive natural convection in an inclined porous square. Two opposing walls of the square cavity are adiabatic; while the other walls are, kept at constant concentrations and temperatures. The Darcy–Forchheimer–Brinkman model is used to solve the governing equations with the Boussinesq approximation. A code written in FORTRAN language developed to solve the governing equations in dimensionless forms using a finite volume approach with a SIMPLER algorithm. The results presented in U-velocity and V-velocity, isotherms, iso-concentration, streamline, the average Nusselt number, and the average Sherwood number for different values of the dimensionless parameters. A wide range of these parameters have been used including; Darcy Number, modified Rayleigh number, Lewis number, buoyancy ratio, and inclination angle. The results show that for opposite buoyancy ratio (N≤-1), the Nu decreases when the Le increases and the Sh increase when the Le increases. For an (N>0), the Nu increases when the Le increases until Le is equal to 1 and then it decreases, also Sh increases when the Le increases

Review of the Effects of Stationary/Rotating Cylinder in a Cavity on the Convection Heat Transfer in Porous Media with/without Nanofluid

“…The authors found that at Ɵ = -45° and Ra =100, the average Nusselt number is the lowest value. Al-Farhany and Turan [19] studied the natural convection in an inclined enclosure. Adiabatic conditions were assumed for the top and bottom walls.…”
