Direct Numerical Simulation of Hypersonic Transition Delay over Carbon/Carbon Ultrasonically Absorptive Coatings

Abstract

The objective of this effort is to initiate development of a high-fidelity predictive numerical tool that can very accurately model the acoustic response of the unique carbon/carbon ultrasonically absorptive coatings (UACs) developed by Wagner et al, DLR Germany, while accounting for complex flow features observed in cross-flow instabilities and non-zero angle-of-attack flow conditions. The tool can be used to guide the design of a new generation of UACs (not limited to C/C) for hypersonic flight conditions of interest to the Air Force.
