Abstract

The study analytically investigates the natural convectionconvection occurring due to the combined effects of concentrationconcentration and temperaturetemperature and buoyancy within a rectangular cavityrectangular cavity featuring uniform massmass and heatheat flow along the verticalvertical sides lined with porous material. The Beavers–JosephBeavers–Joseph (BJBJ) condition is applied at the interface of the porous fluid. Numerous applications use porous liningporous linings, including heatheat exchangers, insulation, solar-energy collection and storage, furnaces, and electronic heatheat management. The analytical method is accurate within the boundary layerboundary layer domain, where convectionconvection plays a role in both heatheat and massmass transfertransfer rates. A linearized OseenOseen solution is formulated for a long rectangular cavityrectangular cavity filled with a mixture characterized by a Lewis numberLewis number, L e = 1 , of one and multiple buoyancy ratios. The solutions are analyzed for various slip parameterslip parameters, buoyancy ratios, and Rayleigh numbersRayleigh number.
