The effect of sloping boundaries on thermal convection is studied theoretically and experimentally in the context of a model in which fluid is contained in a differentially heated rectangular box of small aspect ratio (depth/length), inclined at an angle 8 to the vertical. Like its two limiting cases, Benard convection and convection in the vertical slot, there is a steady laminar twodimensiona...


 Rayleigh-Bénard's convection is a classic problem of heat transfer. Since the 1900s, studies for Newtonian fluids have been widely developed in this field and phenomena well understood. On other hand, complexity non-Newtonian behavior makes number much lower. Among behavior, shear-thinning fluid are even rarer. This work focuses on numerical study natural shear thinning, Rayleigh-Bénard ...

In a composite layer that comprises of porous which is sparsely packed and saturated with two component incompressible fluid above this lays the same fluid, variable heat sources or sinks in both layers double diffusive non-Darcian Benard Marangoni (DDNBM) convection investigated. The upper surface has effects depend on temperature concentration, whereas lower rigid. inverted parabolic, parabol...

The domination by Local Thermal Non-Equilibrium (LTNE) with regard to the onset of Darcy-Rayleigh-Benard-Marangoni (DRBM) convection swayed magnetic field in a composite layer set-up is studied pertinent incompressible fluid. precinct above fluid presumed be free and that below porous rigid. Regular perturbation technique exercised on acquired problem achieve analytical solution taking adiabati...

The physical configuration of the problem Darcy Brinkman (DB) Rayleigh Benard Two-Component (RBTC) Convection in a two-layered system has been investigated for linear, parabolic and inverted salinity gradients with Dufour effect. For fluid layer, upper boundary is free surface tension porous lower rigid. At interface, normal velocity, stress, shear mass, mass flux, heat, heat flux are continuou...
