چکیده

We construct a new numerical method for computing reference numerical solutions to the self{similar solution to the problem of incompressible laminar ow past a thin at plate with suction{blowing. The method generates global numerical approximations to the velocity components and their scaled derivatives for arbitrary values of the Reynolds number in the range 1; 1) on a domain including the boundary layer but excluding a neighbourhood of the leading edge. The method is based on Blasius' approach. Using an experimental error estimate technique it is shown that these numerical approximations are pointwise accurate and that they satisfy pointwise error estimates which are independent of the Reynolds number for the ow. The Reynolds{uniform orders of convergence of the reference numerical solutions, with respect to the number of mesh subintervals used in the solution of Blasius' problem, is at least 0.86 and the error constant is not more than 80. The number of iterations required to solve the nonlinear Blasius problem is independent of the Reynolds number. Therefore the method generates reference numerical solutions with "{uniform errors of any prescribed accuracy.

Transformation Methods for the Blasius Problem and its Recent Variants

Blasius problem is the simplest nonlinear boundary layer problem. We hope that any approach developed for this epitome can be extended to more difficult hydrodynamics problems. With this motivation we review the so called Töpfer transformation, which allows us to find a non-iterative numerical solution of the Blasius problem by solving a related initial value problem and applying a scaling tran...
