Influence of hall current and heat source on MHD flow of a rotating fluid in a parallel porous plate channel 

M. Venkateswarlu, G. Upender Reddy, D. Venkata Lakshmi


This paper examined the MHD and thermal behavior of unsteady mixed convection

flow of a rotating fluid in a porous parallel plate channel in the presence of Hall current

and heat source. The exact solutions of the concentration, energy and momentum equations

are obtained. The influence of each governing parameter on non dimensional velocity, temperature,

concentration, skin friction coefficient, rate of heat transfer and rate of mass transfer at

the porous parallel plate channel surfaces is discussed. During the course of numerical computation,

it is observed that as Hall current parameter and Soret number at the porous channel

surfaces increases, the primary and secondary velocity profiles are increases while the primary

and secondary skin friction coefficients are increases at the cold wall and decreases at the heated

wall. In particular, it is noticed that a reverse trend in case of heat source parameter.

Effect of heat absorption on unsteady MHD flow past an oscillating vertical plate with variable wall temperature and mass diffusion in the presence of hall current

Uday Singh Rajput, Neetu Kanaujia


The present study is carried out to examine the combined effect of heat absorption

on flow model. The model consists of unsteady flow of a viscous, incompressible and

electrically conducting fluid. The flow is along an impulsively started oscillating vertical plate

with variable mass diffusion. The magnetic field is applied perpendicular to the plate. The fluid

model under consideration has been solved by Laplace transform technique. The numerical

data obtained is discussed with the help of graphs and table. The numerical values obtained

for skin-friction have been tabulated. To shorten the lengthy equations in the solution some

symbols have been assumed, which are mentioned in appendix. The appendix is included in

the article as the last section of the manuscript.

Stability of a class

of discrete-time pathogen infection models with latently infected cells

A. M. Elaiw, M. A. Alshaikh


This paper studies the global stability of a class of discrete-time pathogen infection

models with latently infected cells. The rate of pathogens infect the susceptible cells is

taken as bilinear, saturation and general. The continuous-time models are discretized by using

nonstandard finite difference scheme. The basic and global properties of the models are established.

The global stability analysis of the equilibria is performed using Lyapunov method. The

theoretical results are illustrated by numerical simulations.

Analytic treatment for generalized (m+1)-dimensional partial differential equations

Emad A. Az-Zo'bi


In this work, a recently developed semi-analytic technique, so called the residual

power series method, is generalized to process higher-dimensional linear and nonlinear partial

differential equations. The solutions obtained takes a form of an infinite power series which can,

in turn, be expressed in a closed exact form. The results reveal that the proposed generalization

is very effective, convenient and simple. This is achieved by handling the (m+1)-dimensional

Burgers equation.
