MHD Flow, Heat and Mass Transfer due to Axially Moving Cylinder in Presence of Thermal Diffusion, Radiation and Chemical Reactions in a Binary Fluid Mixture

Abstract

In the present paper we have studied the effects of magnetic field, thermal diffusion, thermal radiation and chemical reaction on velocity, temperature and concentration fields about an axially moving isothermal semi infinite solid vertical cylinder in two dimensional incompressible viscous binary fluid mixtures. The governing equations of continuity, momentum, energy and concentration are transformed into non similar boundary layer equations and are solved by using a regular perturbation method together with Matlab's built in solver bvp4c. Numerical solutions for axial velocity component, temperature and concentration of the rarer and lighter component of the binary fluid mixture are obtained on the basis of boundary layer approximation and presented graphically for axial curvature parameter, magnetic field parameter, thermal diffusion parameter, radiation parameter and chemical reaction parameter. It has been found that these parameters affect considerably the flow characteristics. The problem under consideration reduces to the flat plate case when the curvature parameter is absent.

Influence of Chemical Reaction, Magnetic Field and Radiation on Heat and Mass Transfer by Free Convection Flow near the Lower Stagnation Point of an Isothermal Horizontal Circular Cylinder in a Porous Medium Considering Soret and Dufour Effects

“…Ibrahim [20] discussed the effect of the chemical reaction and radiation absorption on the unsteady MHD free convection flow past a semi infinite vertical permeable moving plate with heat source and suction. Sharma and konwar [21] investigated the MHD flow, heat and mass transfer due to axially moving cylinder in presence of thermal diffusion, radiation and chemical reactions in a binary fluid mixture. Ziyauddin and Kumar [22] studied the MHD heat and mass transfer free convection flow near the lower stagnation point of an isothermal Cylinder imbedded in Porous Domain with the presence of Radiation.…”

Study on Periodic MHD Flow with Temperature Dependent Viscosity and Thermal Conductivity past an Isothermal Oscillating Cylinder

“…By taking binary fluid mixture a regular perturbation method has been used to solve MHD flow, heat and mass transfer due to auxiliary moving cylinder in the presence of thermal diffusion, radiation and chemical reactions by Sharma et al (2015) [9]. They used regular perturbation method to solve the above problem and with the increases in the value of magnetic field parameter decreases velocity which has been concluded by Sharma et al (2015) [9]. In a porous medium by using Darcy-Forchheimer model the main aim of that work was to investigate the ef- [12].…”
