Abstract

Analysis is carried out to study the two dimensional steady flow over a wedge. Furthermore, using a similarity variable, the governing flow equations are transformed to a nonlinear coupled differential equation which is solved numerically. A comparison of the solution technique is carried out in previous work and the results are found to be in good agreement. Numerical results for the shear stress and skin friction are presented for different physical parameters. The analysis of the obtained result shows the flow is significantly influenced by these parameters.
