D. Thesis Highlights: My Ph. D. thesis modeled unsteady convective heat and mass transfer flow along a wedge with thermophoresis and various flow conditions. The governing non-linear partial differential equations have been reduced to a set of non-linear ordinary differential equations by introducing similarity transformations. The resulting local similarity equations unsteady flows have been solved numerically by applying Nachtsheim-Swigert shooting iteration technique along with sixth order Runge-Kutta integration scheme. The results of these solutions were presented graphically as well as in tabulated form and discussed from the physical point of view.  
  1. Phil. Thesis Highlights: My M. Phil. thesis investigated effects of temperature dependent thermal conductivity on magnetohydrodynamic free convection flow along a vertical flat plate with heat conduction. The governing equations with associated boundary conditions for this phenomenon are converted to dimensionless form using suitable transformations, the governing equations containing the equation of continuity, momentum and energy. The transformed non-linear ordinary partial differential equations are then solved using the implicit finite difference method with Keller-box scheme. Numerical results of the velocity profiles, temperature profiles, skin friction co-efficient and surface temperature distribution for different values of various parameters.
