Unsteady transonic flow computations

A. Richard Seebass, N. YU, Kin Yip Fung

Abstract

The effects of unsteady modes of motion on two-dimensional transonic flows are investigated. Numerical algorithms that treat shock waves as moving discontinuities are described for nonlinear and time-linearized perturbation flows. Results for transonic flow past an NACA 64A006 airfoil experiencing harmonic motions in one of several modes are presented. (Author)
