Computational study of 3D problems of supersonic aerodynamics on the basis of Euler equations

摘要

The results of numerical computations of three-dimensional supersonic flows in the vicinity of different configurations on the basis of the Euler equations are presented. The flowfield properties, surface pressure and lift coefficient variations for different wing configurations with subsonic and supersonic sharp-leading edges are analyzed-in wide range of the angles of attack /spl alpha/=0-14/spl deg/ and Mach number M/sub /spl infin//=2,25-4. The sonic-boom-parameters for the supersonic civil transport Tu-144 are estimated. The supersonic flows over the bodies of revolution in the presence of flat and curved surfaces are considered. A comparison of the computations with experimental data are demonstrated.
