Analysis of Calculated Three-Dimensional Inviscid Flow Fields with Embedded Shock Waves (Presentation of a Field Solution), Part 1

摘要

Flow fields around a number of different body contours, and calculated by means of a finite difference procedure are analyzed. The investigated fields are three dimensional in general. The analysis is carried out with the air of characteristics, streamlines, lines of constant static pressure and static density, and with the velocity vectors at the gridpoints in planes phi = const. Planes z = const lines of constant cross flow Mach number and the velocity vectors of the crossflow at the gridpoints are presented. The interval of freestream Mach number considered is 1.4 M sub infinity or = M or = 3, and the range of angle of attack alpha is up to 20 deg. The quality of the finite difference solution used is demonstrated by comparison with experimental data. The accuracy attained especially for the detection of the position and the contour of embedded shocks is very good.
