This article presents a numerical solution for the flow of a Newtonian fluid over an impermeable
stretching sheet with a power-law surface velocity, slip velocity, and variable thickness.
The flow is caused by nonlinear stretching of the sheet. The governing partial differential equations
are transformed into a nonlinear ordinary differential equation with appropriate boundary conditions
for various physical parameters. The remaining ordinary differential equation is solved numerically
by using the Chebyshev spectral method. The effects of the slip parameter and the wall thickness
parameter on the flow profile and local skin-friction are presented. A comparison of obtained numerical
results is made with previously published results in some special cases, and excellent agreement
is noted.
