We have investigated effect of throughflow and gravity modulation on double diffusive convection with couple-stress fluid saturated porous media. Applying the Landau model, we derived finite amplitude in presence modulation. The a parameter produces both diminishing enhancing heat mass transfer layer. To present results used Mathematica to obtain Nusselt number Sherwood numbers numerically. Fur...

Numerical investigation is carried out to predict the entropy generation for combined natural convection heat and mass transfer in a two dimensional porous cavity subjected to a magnetic field. The Darcy model is used in the mathematical formulation of the flow in porous media. The mathematical model is derived in dimensionless form. The governing parameters arise in the mathematical model are ...

The present study aims to investigate the of double-diffusive convection on peristaltic flow under assumption long wavelength and low Reynolds number. mathematical modelling for a two-dimensional flow, along with double diffusion in nanofluids is considered. motivation research work analyze effects thermal radiation through porous medium nonuniform channel. heat flux linear approximation employ...

Onset of Double Diffusive Rayleigh-Benard-Magneto (DDRBM) convection is studied for a double layered system composed incompressible fluid confined by adiabatic rigid peripheries under the governance Local Thermal Non-Equilibrium (LTNE). Result acquired problem obtained analytically through mode Regular Perturbation. Consequence physical factors such as solid phase thermal expansion ratio, diffu...

Double diffusive natural convection of carbon dioxide in two-dimensional cavities filled with brine saturated porous media is numerically investigated in this study. Vertical gradients of carbon dioxide concentration and temperature are imposed across the height of the cavity. The objective is to understand the dissolution of carbon dioxide through natural convection process over long period of...

A computational study has been made for a three dimensional double diffusive convection with molten Pb-Sn by using finite volume method. In this work, two vertical walls have different temperature and different concentration while remaining walls are adiabatic. Buoyancy ratio, which changes between N = -0.1 and -10, is the main governing parameter during work. Other parameters are taken as fixe...
