In the present paper analysis is carried out to study on an unsteady magnetohydrodynamic flow between two parallel plates with one in uniform motion and the other plate at rest. We also incorporated the uniform suction at stationary plate. The applications of magnetohydrodynamic cover a wide range of engineering areas as power generators, aerodynamics heating, petroleum industry, cooling system, purification of crude oil, separation of matter from fluid, fluid droplets and sprays. We also discussed the physical characteristics of longitudinal and transverse velocity and pressure distributions. The arising set of partial governing differential equations (PDEs) of the flow is solved by similarity transformation. Analytical expression is given for the velocity field and the effects of the various parameters entering into the problem are discussed with the help of graph.Keywords
MHD, Parallel Plates, Pressure Gradient, Reynolds Number, Hartmann Number.

In this article, we have studied the flow and heat transfer in magneto hydrodynamic Tangent hyperbolic fluid with exponentially heat source/sink. The partial differential equations governing the problem have been reduced by similarity transformations into the ordinary differential equations. Numerical solutions are transferred out by using Runge-Kutta Shooting technique. The effects of various governing parameters on the flow quantities are demonstrated graphically. The solution depends on various interesting parameters including the friction factor coefficient and local Nusselt numbers for the Sakiadis and Blasius flow cases. It is determined that the rate of heat transfer is extremely high in Blasius flow case when compared with Sakiadis flow case.Keywords

This paper comprehensively analyses the momentum, heat and mass transfer behavior of a heat source or sink on magnetohydrodynamic tangent hyperbolic dusty fluid in suspension of convective conditions. The governing partial differential equations of the flow, heat transfer are transformed into non-linear ordinary differential equations by using self-similarity transformations, which are further solved numerically using the Runge-Kutta and Newton’s method. The effects of various non-dimensional governing parameters on velocity and temperature distributions are discussed with the help of graphs. Furthermore, the effects of these parameters on local friction factor coefficient and heat transfer rate are also discussed and presented through tables.Keywords

The present study emphases steady boundary layer flow and heat transfer of a hyperbolic tangent fluid flowing over a vertical exponentially stretching cylinder in its axial directionwith non-uniform heat source/sink. Proposed mathematical model has a tendency to characterize the effect of the non-uniform heat source/sink. The non-linear ordinary differential equations are solved using the Runge-Kutta Feldberg (RKF) integration method. The characteristics of velocity and temperature boundary layers in the presence of Weissennberg number We are presented for different physical parameters such as heat source/ sink parameter, Reynolds number Re, the Prandtl number Pr , the Weissennberg number We and the natural convection parameter λ , magnetic field parameter and porosity parameter K . Moreover, the friction factor coefficients, Nusselt number are also estimated and discussed for aforesaid physical parameters. In addition, the rate of heat transfer rate is higher in case of We = 0.5 compared toWe = 0 with n = 0.2 .Keywords

The present problem is the steady boundary layer flow and heat transfer of a hyperbolic tangent fluid flowing over a vertical exponentially stretching cylinder in its axial direction with heat source or sink. After applying usual boundary layer with a suitable similarity transformation to the given partial differential equations and the boundary conditions, a system of coupled nonlinear ordinary differential equations is obtained. This system of ordinary differential equations subject to the boundary conditions is solved with the help of Runge-Kutta method along shooting technique. The effects of the involved parameters such as Reynolds number, Prandtl number, Weissennberg number, power law index parameter and the natural convention parameter are presented through the graphs. The associated physical properties on the flow and heat transfer characteristics that are the skin friction coefficient and Nusselt number are presented for various parameters.Keywords

A theoretical analysis performed for investigating steady boundary layer flow of magnetohydrodynamic flow over cylinder with heat source/sink. Proposed mathematical model has a tendency to characterize the effect of magnetohydrodynamic flow over cylinder heat source/sink. The non-linear ordinary differential equations are solved using the Runge-Kutta method. The characteristics of velocity and temperature boundary layers for different physical parameters such as heat source parameter QH , Reynolds number Re, the Prandtl number Pr , the magnetic field parameter M and power law index parameter n . Moreover, the local friction factor coefficients, Nusselt number are also estimated and discussed for aforesaid physical parameters. It is observed that heat transfer rate increases with in power law index parameter and magnetic field parameter while decrease in power law index parameter and Reynolds number.Keywords

This study presents the effect of magnetic field on the flow and heat transfer of an incompressible Carreau fluid over stretching sheet with uniform suspended dust particle. The relevant governing equations are first simplified under usual boundary layer assumptions and then transformed into ordinary differential equations (ODEs) by similarity transformations. The transformed ordinary nonlinear differential equations are solved numerically by R-K with Shooting Technique. The effects of certain parameters on the dimensionless velocity, temperature profile are presented graphically and also calculated the thermo physical properties of the flow friction factor, Local Nusselt and Sherwood number. The important outcome of this study is magnetic parameter enhances the temperature profile of fluid phase but decreases the velocity of both fluid and dust phase.Keywords
