Laminar Boundary Layer Mixed Convection Flow over a Plate with Variable Viscosity and Prandtl Number

Abstract

This thesis presents the numerical investigation of laminar mixed convection fluid flow moving on stretching surface with variable fluid properties and suitable bound ary conditions. Although many investigations have been made, only those relevant to present work are mentioned in this thesis. The viscous fluid and Prandtl number com binedly impact the buoyancy flow moving on vertical flat plate. In this way, i have described the various non-dimensional parameter effects of Magnetic parameter (H), Lewis number (Le), Reynolds number, Thermophoresis (Nt), Grashof number, Brown ian motion (Nb) and viscous ratio parameter on velocity profiles, temperature profiles, skin friction and heat transfer coefficients with time dependent variables. The coupled partial differential equations are discretized using finite difference scheme and solved by Varga s algorithm with Quasilinearization technique. The impact of the suction and injection parameter moving on stretching sheet is discussed. The thermal radiation of nanofluid flow moving on vertical flat plate is determined. The computed results of various non-dimensional parameters are analyzed numerical and graphically.
