Analytic and Numerical Investigation of the Convergence for the Adaptive-Wall Concept

Abstract

Convergence of the iteration for the adaptive wall concept is analytically proved for two-dimensional and axisymmetric subsonic flows. One- step convergence formulae which determine the unconfined boundary conditions directly from two measured flow variables at the measuring surface are presented to accelerate the iterative procedure. The application of the one-step formulae to numerical examples of an NACA 0012 airfoil illustrates the capability of these formulae for subcritical as well as supercritical flows. (Author)
