This paper deals with the effect of heat and mass transfer with chemical reaction on MHD oscillatory flow through porous medium in the presence of heat source/sink in an asymmetric channel. Based on some simplifying assumptions, the governing momentum, energy and diffusion equations are solved and the analytical solutions for fluid velocity, temperature distribution, mass concentration, skin fr...

Laminar and turbulent mixed convection heat transfer of water/Cu nanofluids in a rectangular shallow cavity was studied utilizing a two-phase mixture model. The upper movable lid of the cavity was at a lower temperature compared to the bottom wall. Simulations were performed for Grashof numbers of 105 (laminar flow) and 1010 (turbulent flow) for Richardson numbers from 0.03 to 30, and nanoparti...

Dimensionless numbers are of key importance in parametric analysis engineering problems. They also extremely useful understanding the similarity among problems belonging to different unit operations. Very large number dimensionless used heat and mass transfer, fluid mechanics, food dairy processing. Well-known numbers, like Reynolds, Prandtl, Nusselt, Grashof, Biot, Furier, Power, Lews Laplace ...

This paper examines the MHD convection slip fluid flow with radiation and heat deposition in a channel in a porous medium. The dimensionless governing equations were solved using the perturbation technique to obtained the analytical expressions of velocity, temperature and concentration profiles of the fluid with expression of Skin friction, mass and heat transfer in terms of Shear stress, Nuss...

The unsteady free convection flow with thermal radiation past a vertical plate with Newtonian heating has been studied. The governing equations have been solved numerically by the implicit finite difference method of CrankNicolson's type. The variations of the fluid velocity and temperature are presented graphically. It is found that the fluid velocity decreases near the plate and it incre...

Turbulent mixed convection of a nanofluid (water/Al2O3, Φ=.02) has been studied numerically. Two-phase mixture model has been used to investigate the effects of nanoparticles mean diameter on the flow parameters. Nanoparticles distribution at the tube cross section shows that the particles are uniformly dispersed. The non-uniformity of the particles distribution occurs in the case of large nano...
