in present paper, a numerical analysis for a rectangular cavity filled with a anisotropic porous media has been studied. it is assumed that the horizontal walls are adiabatic and impermeable, while the side walls of the cavity are maintained at constant temperatures and concentrations. the buoyancy force that induced the fluid motion are assumed to be cooperative. in the two extreme cases of he...

The paper studied the transient convection fluid flow with heat flux in an infinite vertical plate with chemical mass transfer. The dimensionless governing equations were solved using the Laplace transform method 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 stres...

DEAR EDITOR, Early identification and prevention of Chronic Kidney Disease (CKD) has been emphasized as an area of importance by the National Service Framework for Renal Services of the UK. Over 2% of the total National Health Service (NHS) UK budget is spent on renal replacement therapy for those with established renal failure, and on an average 30% of patients with advanced renal failure are ...

In this article, entropy generation on viscous nanofluid through a horizontal Riga plate has been examined. The present flow problem consists of continuity, linear momentum, thermal energy, and nanoparticle concentration equation which are simplified with the help of Oberbeck-Boussinesq approximation. The resulting highly nonlinear coupled partial differential equations are solved numerically b...

The investigation of the transient convection fluid flow with heat and mass flux in a fixed vertical plate with radiation is presented. The dimensionless governing equations were solved using the Laplace transform method to obtained the analytical expressions of velocity, temperature and concentration profiles of the fluid. Skin friction, Nusselt number and Sherwood number are computed respecti...

This paper presents an investigation for bioconvection heat transfer of a nanofluid containing gyrotactic microorganisms over a stretching sheet, in which the effects of radiation, velocity slip and temperature jump are taken into account. The nonlinear governing equations are reduced into four ordinary differential equations by similarity transformations and solved by Homotopy Analysis Method ...

Problem statement: A steady two-dimensional free convection and mass transfer flow past a continuously moving semi-infinite flat plate is studied theoretically, by taking into account the viscous dissipation effect. Approach: The governing equations are transformed into a set of simultaneous ordinary differential equation by using suitable similarity transformations. The coupled differential eq...

I have developed an alternative numerical approach to study mass transfer from a stationary core-shell reservoir under channel flow conditions. I use the lattice Boltzmann method to compute both the solvent fluid flow and the diffusion and advection of the solute. I have investigated the impact of the flow by reporting mass transfer quantities such as the instantaneous solute concentration and ...
