The present work. details the numerical simulation of forced convective, incompressible flow in a channel with an array of heated obstacles attached to one wall. Three levels of Nusselt numbers are emphasized in this systematic analysis: local distributions along the obstacle exposed faces, mean values for individual faces, and overall obstacle mean values. This study details the effects of var...

The effect of time-periodic oscillations of the RayleighBénard system on the heat transport in dielectric liquids is investigated by weakly nonlinear analysis. We focus on stationary convection using the slow time scale and arrive at the real GinzburgLandau equation. Classical fourth order Runge-kutta method is used to solve the Ginzburg-Landau equation which gives the amplitude of convection a...

The combined effects of mass transfer and rotation on unsteady magnetohydrodynamic (MHD) free convection flow in a porous medium past an infinite inclined plate with ramped wall temperature has been investigated. The effects of thermal diffusion and heat absorption are also observed. Exact solution using Laplace transforms technique has been obtained for the velocity, temperature and concentrat...

The present study aim to study the effects of variable thermal conductivity and heat generation on flow of a viscous incompressible electrically conducting fluid in the presence of uniform transverse magnetic field, thermal radiation, porous medium, mass transfer and variable free stream near a stagnation point on a non-conducting stretching sheet.

In the present paper, an analysis is carried out to study the free convection, thermal radiation and mass transfer effects on an unsteady flow of a viscous incompressible micropolar fluid over a vertical moving porous plate immersed in a porous medium with time varying suction velocity. The plate moves with the constant velocity in the longitudinal direction, and the free stream velocity follow...

The present study investigates the unsteady, two dimensional, laminar flow of a nanofluid over a stretching sheet with thermal dispersion in the presence of MHD and variable suction is studied.

Using the similarity transformations, the governing equations have been transformed into...

In this paper we analyze the combine influence of radiation and dissipation on the convective heat and mass transfer flow of a viscous fluid through a porous medium in a rectangular cavity using Darcy model. Making use of the incompressibility the governing non-linear coupled equations for the momentum, energy and diffusion are derived in terms of the non-dimensional stream function, temperatur...

A uniform magnetic field is applied in the direction normal to the moving plate. Also, the plate is cons...

The combined effects of Soret and Dufour on an unsteady mixed convection magnetohydrodynamics heat and mass transfer in a micropolar fluid saturated Darcian porous medium in the presence of thermal radiation, heat generation, Ohmic heating and chemical reaction have been investigated. The transformed boundary layer equations are solved numerically by applying Keller-box method. Comparison of nu...
