CHEBYSHEV SOLUTION OF STAGNATION POINT FLOW

An expansion procedure using Chebyshev polynomials based on the El-Gen di method [1] is proposed to solve nonlinear boundary value problems g overning the flow of an incompressible viscous fluid in the vicinity o f a forward stagnation point at a blunt body. This method is accomplis hed starting with a Chebyshev approximation for the higher order deriv atives and generating approximations to the lower order derivatives. T he numerical solutions are presented for different cases. The results obtained in this investigation are found to be comparable with the res ults reached by Cheng et al.
