Transonic Flow Past a Wedge Profile With Detached Bow Wave - Details of Analysis
Abstract
Details are given of calculations of the flow with detached bow wave past a doubly symmetrical, double-wedge profile at zero angle of attack. The results of these calculations have been described previously in NACA TN 2339. The mixed flow over the front of the profile is determined by the solution of a boundary value problem for the transonic small disturbance equation in the hodograph plane. The solution is obtained by the use of finite difference equations and relaxation techniques. The methods follow established lines except for the somewhat novel treatment of the boundary conditions along the shock polar and sonic line. The purely supersonic flow over the rear of the profile is determined by means of the method of characteristics specialized to the transonic small-disturbance theory.
