Abstract
In this thesis, a finite difference solution to the coupled nonlinear system of partial differential equations governing the flow of water at 40C past impulsively started infinite vertical
plate is presented.For the numerical results,the governing boundary layer equations are
transformed in to non-dimensional form using non-dimensional quantities. Representa
tive velocity and temperature profiles were graphed and the numerical values of the Skin
friction and the Nusselt numbers were calculated and also the effects of different system
parameters, such as the Grashof number, Prandtl number, Eckert number and time on
the velocity, temperature, skin friction, and Nusselt numbers, were examined in detail.
It is observed that, due to fall in the temperature of the fluid, there is fall in the velocity
but an increase in the skin-friction. Furthermore, the skin friction and Nusselt number
decreases with increasing Eckert number (E) and Grashof number (G
