Heat Transfer in Boundary Layer Viscolastic Fluid Flow Over Anexponentially Stretching Sheet
The paper presents the study of momentum and heat transfer characteristics in a visco-elastic boundary layer fluid flow over
an exponentially stretching continuous sheet with non-uniform heat source. The flow is generated solely by the application of
two equal and opposite forces along the x-axis such that stretching of the boundary surface is of exponential order in x and
influenced by uniform magnetic field applied vertically. The non-linear boundary layer equation for momentum is converted
into ordinary differential equation by means of similarity transformation. Approximate analytical similarity solutions is
obtained for the dimensionless stream function and velocity distribution function after transforming the boundary layer
equation into Riccati type and solving it sequentially. Heat transfer equation is then solved using Runge-Kutta fourth order
method. The accuracy of the analytical solutions is also verified by comparing the solutions obtained to those in literature
when Hartmann number is zero. The effects of various physical parameters on velocity, skin friction, temperature and
Nusselt number profiles are presented graphically
