Effects of some thermo-physical parameters on free convective heat and mass transfer over a vertical stretching surface at the lowest level of heat energy in the presence of suction are investigated in the presence of suction. At constant function of thermal conductivity, the dynamic viscosity of the fluid is assumed to vary as a linear function of temperature. A similarity transformation is applied to reduce the governing equations to a coupled ordinary differential equations corresponding to the momentum, energy and concentration equations. These equations along with the boundary conditions are also solved numerically using shooting method along with Runge-Kutta-Gill method. The effects of thermo-physical parameters on the velocity, temperature and concentration profiles are graphically shown. It is found that with an increase in the value of temperature-dependent fluid viscosity parameter, the velocity increases while the temperature and concentration decrease across the flow region. Dufour, Soret, Frank-Kamenetskii, Prandtl and Schmidt numbers activation energy also has an effect. Numerical data for the local skin-friction coefficient, the local Nusselt number and the local Sherwood number have been tabulated for various values of certain parameter conditions.

The objective of this article is to present the dynamics of an Upper Convected Maxwell (UCM) fluid flow with heat and mass transfer over a melting surface. The influence of melting heat transfer, thermal and solutal stratification are properly accounted for by modifying the classical boundary conditions of temperature and concentration respectively. It is assumed that the ratio of inertia forces to viscous forces is high enough for boundary layer approximation to be valid. The corresponding influence of exponential space dependent internal heat source on viscosity and thermal conductivity of UCM is properly considered. The dynamic viscosity and thermal conductivity of UCM are temperature dependent. Classical temperature dependent viscosity and thermal conductivity models were modified to suit the case of both melting heat transfer and thermal stratification. The governing non-linear partial differential equations describing the problem are reduced to a system of nonlinear ordinary differential equations using similarity transformations and completed the solution numerically using the Runge-Kutta method along with shooting technique. For accurate and correct analysis of the effect of variable viscosity on fluid flow in which (Tw or Tm)

 Approximate Solution To Laminar Falling Liquid With Variable Viscosity Along An Inclined Heated Plate

 O. K. Koriko And A .J. Omowaye

 2011

This paper examines the steady-state solution of a laminar falling liquid film with variable viscosity along an inclined heated plate. The existence and uniqueness of solution to this problem was investigated and it was found that the problem has a unique solution. Numerical solution via shooting techniques were employed in tacking the non-linear coupled momentum and energy balance equations. The Brinkman number and variable viscosity parameter play a prominent roll in the construction of the numerical solution. The velocity and temperature profiles of the liquid film are displayed in graphs.
