Low Density Real Gas Flows About Hypersonic Vehicles.
Abstract
This document represents the final report for Air Force contract F33615-86-C-3006, 'Low Density Real Gas Flows About Hypersonic Vehicles.' The focus of this contract was the development of a computer code capable of predicting trends in hypersonic vehicle flowfield properties to support design trade studies for improved hypersonic vehicles. This report provides details of the Hyper sonic Low Density Analysis (HYLDA) code developed for this contract. Included in this report are summaries of the HYLDA code, details of the HYLDA fully-coupled Navier-Stokes/finite rate chemistry solution algorithm, details of the thermochemistry models used by the code, and results from three Government- supplied demonstration cases. Code summaries discussed include code features, code design, and multiprocessing capability, while the algorithm discussion includes governing equations, development of the solution algorithm, and boundary conditions. The thermochemistry discussion includes details of the chemistry model transport properties model, and species thermodynamics properties modal developed for the HYLDA code The Government-supplied demonstration cases consist of a Mach 16 wedge flow, a Mach 12 biconic, and a Mach 5 catalytic hemisphere. Hypersonic low-density flows, Navier-Stokes/ finite rate chemistry algorithm, implicit algorithm with Gauss-Seidel line relaxation and flux splitting, thermochemistry models, parallel processing.
