Continuing developments in high-speed finned-missile technology require new accurate and computationally fast numerical techniques for predicting the associated viscous flows at small-to-moderate angles of attack over a wide range of low-to-high Mach

A new coupled-chemistry PNS scheme has been developed to study 3D hypersonic reentry flows over sphere cones at small angles of attack. A new quasi-steady ablation model for Teflon was used to predict ablative reentry flow fields under laminar, trans

The nonequilibrium viscous shock-layer (VSL) solution scheme is revisited to improve its solution accuracy in the stagnation region and also to minimize and control errors in the conservation of elemental mass. The stagnation-point solution is improv

A 3D parabolized Navier-Stokes (PNS) technique is examined in terms of applications to equilibrium-air and perfect-gas hypersonic flows at different Mach numbers and angles of attack. The method renders sublayer approximation unnecessary, and treats

A parabolized Navier-Stokes (PNS) scheme has been developed to study perfect-gas and equilibrium-air hypersonic flows around three-dimensional configurations. This numerical scheme is unconditionally time-like in the subsonic as well as the supersoni

In this paper we discuss the background and applications of a new unified series of codes for predicting large angle-of-attack viscous supersonic/hypersonic flows over spherically blunt re-entry vehicles and decoys. The solution scheme used involves

In this study, a new three-dimensional fully iterative parabolized Navier-Stokes (PNS) scheme has been developed to study perfect-gas or equilibrium-air viscous hypersonic flows around ballistic re-entry configurations at large angles of attack. This
