Calculation of Unsteady Two-Dimensional Supersonic Flow by the Method of Characteristics.
Abstract
A method of characteristics for unsteady two-dimensional flow is presented. The method is applied to flow fields over a blunt-nosed airfoil in a supersonic free stream. The compatibility relation is derived first. Then the method of solution is presented. Three types of numerical examples are presented and discussed. The first type establishes the stability of the numerical scheme. The second type consists of the unsteady flow fields over an NACA 0024 airfoil in harmonic lunging, pulsating, and pitching motions. The third type represents application to steady flow problems and includes the calculation of the flow field over an NACA 0009 airfoil at a low supersonic speed of M = 1.2
