Computation of Supersonic Flows over Three-Dimensional Configurations

Kuo-Yen Szema; W. L. Riba; V. Shankar; J. J. Gorski

An aerodynamic prediction technique based on the steady form of the full-potential equation has been applied to a variety of three-dimensional supersonic flow problems exhibiting embedded subsonic regions. A conservative switching scheme is employed to transition from the supersonic relaxation algorithm, and vice versa. Numerical solutions are obtained for a number of complex configurations, including advanced tactical fighter, Langley canard-wing fighter configuration, isolated shuttle orbiter, and mated shuttle orbiter configuration with external tank. The computed results are in good agreement with available experimental data.

Steady and unsteady nonlinear flow treatment using the full potential equation

Vijaya Shankar; Kuo-Yen Szema; Joseph Gorski; Hiroshi Ide

The steady and unsteady forms of the full potential equation are treated using implicit numerical methods based on the approximate factorization technique or relaxation concepts. Problems solved include supersonic flows over complex configurations with embedded subsonic regions, and flows over airfoils and spheres at all Mach numbers. The treatment involves time linearization of density, flux linearization in the marching direction, theory of characteristic signal propagation, steady and unsteady wake treatment, flux biasing concepts for artificial viscosity, and unsteady far-field based on the Riemann invariants.
