Hypersonic viscous flows in a streamline coordinate system
Abstract
A method based on the use of the parabolized Navier-Stokes equations (PNS) has been developed for computing the three-dimensional laminar hypersonic viscous flowfield over a body at very high angles of attack (up to 90 deg). In accordance with the proposed approach, the viscous flow equations are parabolized along the surface streamline direction, rather than in the body-generator coordinate direction, which almost completely eliminates the restriction on the angle of attack of a flight vehicle. A comparison with the results of the conventional body-generator PNS method indicates that the streamline approach, SLPNS, proposed here can accurately solve the flowfield with approximately the same computer time requirements.
