Abstract
Solutions of the Euler equations are presented for M=1.5 flow past a 70 degree swept delta wing. At an angle of attack of 10 degrees, strong leading edge vortices are produced. Two computational approaches are taken based upon 1) fully three-dimensional and 2) conical flow theory. Both methods utilize a finite-volume discretization solved by a pseudo-unsteady multistage scheme. Results from the two approaches are in good agreement. Computations have been done on a 16 million word CYBER 205 using 196 x 56 x 96 and 128 x 128 cells for the two methods. A sizable data base is generated, and some of the practical aspects of manipulating it are mentioned. The results reveal many interesting physical features of the compressible vortical flow field, and also suggest new areas needing research.
