Abstract:
In this dissertation, the effects of temperature dq)cndent lhenna1 conductivity on the
coupling of conduction and Joule heating with viscous di>sipation and
Magnctohydrodynamic free convection flow along a vertical flat plate have been
investigated numerically. A steady laminar two dimensional MHD free convection flow is
considered here. TIle gc}\'cming equations contain the equation of continuity. momentum
and energy. TIlcse equations with associated bOlLndalYconditions for thi, phenomenon are
converted to dimensionless fonn using suitable transformations. The transformed nonlinear
ordinary differential equations are then solved using the imphcit tillite difference
method wilh Keller-box scheme. FORTRAN 90 is used to perform computational job ami
