On solving boundary value problem in fluid mechanics by Fourier’s method: Wall Interference of Transonic Wind Tunnels

Abstract

The influence of perforated walls of transonic wind tunnels at two-dimensional investigations by employing the advanced numerical method for solving Dirichlet’s problem formulated for a rectangle of wind tunnel’s work section is given in this paper. To demonstrate the appropriateness of the presented advanced algorithm for calculation of transonic wind tunnel wall interference at two-dimensional investigations, the algorithm has been applied to the aerodynamic experimental results from investigations of BGK 1 airfoil obtained in NAE (Canada). The comparative results of calculations for the same test which were performed by finite difference method (obtained in USA, Canada, Japan, France and Holland) and by the presented advanced numerical method (obtained at the University of Belgrade) are given as well.
