Chebyshev finite difference method for the effects of chemical reaction, heat and mass transfer on laminar flow along a semi infinite horizontal plate with temperature dependent viscosity

The effect of variable viscosity, chemical reaction, heat and mass transfer on laminar flow along a semi infinite horizontal plate has been analyzed. The fluid viscosity is assumed to vary as an inverse linear function of temperature. By means of the similarity solutions, deviation of the velocity, concentration and temperature fields as well as the skin friction and heal transfer results from their constant values are determined numerically by using Chebyshev finite difference method. The effects of variable viscosity, chemical reaction and Schmidt number parameters on the velocity, concentration and temperature profiles have been studied.

Effect of variable viscosity on laminar convection flow of an electrically conducting fluid in uniform magnetic field

The flow of a viscous incompressible electrically conducting fluid on a continuous moving flat plate in presence of uniform transverse magnetic field, is studied. The flat plate which is continuously moving in its own plane with a constant speed is considered to be isothermally heated. Assuming the fluid viscosity as an inverse linear function of temperature, the nature of fluid velocity and temperature in presence of uniform magnetic field are shown for changing viscosity parameter at different layers of the medium. Numerical solutions are obtained by using Runge-Kutta and Shooting method. The coefficient of skin friction and the rate of heat transfer are calculated at different viscosity parameter and Prandt l number. .

Effects of magnetic field and variable viscosity on forced non‐darcy flow about a flat plate with variable wall temperature in porous media in the presence of suction and blowing

This paper presents a study of the effect of a magnetic field and variable viscosity on steady two‐dimensional laminar non‐Darcy forced convection flow over a flat plate with variable wall temperature in a porous medium in the presence of blowing (suction). The fluid viscosity is assumed to vary as an inverse linear function of temperature. The derived fundamental equations on the assumption of small magnetic Reynolds number are solved numerically by using the finite difference method. The effects of variable viscosity, magnetic and suction (or injection) parameters on the velocity and temperature profiles as well as on the skin‐friction and heat‐transfer coefficients were studied. It is shown that the magnetic field increases the wall skin friction while the heat‐transfer rate decreases.

Effects of radiation and variable viscosity on a MHD free convection flow past a semi-infinite flat plate with an aligned magnetic field in the case of unsteady flow

The effect of radiation and variable viscosity on a MHD free convection flow past a semi-infinite flat plate with an aligned magnetic field has been studied in the case of unsteady flow. The plate is moved with a constant velocity, which is in the same or opposite direction to the free stream velocity. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The effect of the induced magnetic field has been included in the analysis. The governing partial differential equations have been solved numerically using the finite difference method. The velocity, the x-component of the induced magnetic field and heat transfer characteristics of the flow are determined

Thermal radiation and buoyancy effects on MHD free convective heat generating flow over an accelerating permeable surface with temperature-dependent viscosity

The paper presents a study of the flow of a viscous incompressible fluid over an accelerating permeable surface with temperature-dependent viscosity, taking into account the effect of thermal radiation and thermal buoyancy in the presence of a magnetic field. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The governing equations for laminar free convection of fluid are changed to dimensionless ordinary differential equations by similarity transformation. They are solved by a shooting method. The effects of various parameters on the velocity and temperature profiles as well as the skin friction coefficient and wall heat transfer are presented graphically and in tabulated form.

Radiation Effect on Convective Heat Transfer in an Electrically Conducting Fluid at a Stretching Surface with Variable Viscosity and Uniform Free Stream

The problem of free convection heat transfer characteristics in an electrically conducting fluid is investigated near an isothermal sheet. This has been done under the combined effect of buoyancy and radiation in the presence of uniform transverse magnetic field. The sheet is linearly stretched in the presence of a uniform free stream of constant velocity and temperature. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The effects of free convection and internal heat generation or absorption are also considered. Fundamental equations are derived on the assumption of small magnetic Reynolds number. The resulting coupled nonlinear differential equations are solved numerically and the velocity and temperature profiles as well as the local Nusselt number and skin-friction coefficient are computed for various values of magnetic field, radiation, heat source and variable viscosity.

Free Convection Flow from a Vertical Isothermal Cone with Temperature-Dependent Viscosity

Abstract This paper reports a study of the effect of variable viscosity, expressed as an inverse linear function of temperature, on the free convective heat and fluid flow past a vertical isothermal cone. By similarity analysis together with the boundary layer assumptions, this complex problem is reduced to a system of coupled nonlinear ordinary differential equations. The resultant boundary layer equations are integrated numerically to obtain the flow field and the temperature distribution for selected influence parameters such as the viscosity parameter θ r and the Prandtl number Pr. The viscosity parameter θ r plays a prominent role in both flow field and heat transfer. In this paper, θ r relates to the reciprocal of the temperature difference between the heated surface and the ambient. The calculated results indicate that some variations will be introduced in the heat transfer rate as well as the skin friction coefficient.
