The Effects of Some Thermo-physical Properties of Fluid on Heat and Mass Transfer Flow Past Semi-infinite Moving Vertical Plate with Viscous Dissipation

Abstract

This paper examines the effect of some thermo-physical properties of fluid on heat and mass transfer flow past semi-infinite moving vertical plate. The fluid considered is optically thin such that the thermal radiative heat loss on the fluid is modeled using Rosseland approximation.The governing partial differential equations in dimensionless forms are solved numerically using the Method of Lines (MOL). The velocity, the temperature, and the concentration profiles of the flow are discussed numerically and presented. Numerical values of the skin-friction coefficient, Nusselt number, and Sherwood number at the plate are discussed numerically for various values of thermo-physical parameters and they are presented by the tables.The result shows that an increase in thermal radiation causes increase in velocity and temperature profiles of the flow, thus, the thermal radiation intensifies the convective flow. Also, an increase in Soret number causes increase in velocity and concentration profiles of the flow while the effect is negligible on temperature profile distribution. Similarly, an increase in Dufour number causes increase in velocity and temperature profiles of the flow.
