Development of Novel Molecule-Based Measurement Techniques to Characterize Aero-Thermo-Elastic Interactions of Super-/Hyper-sonic Flows and Solid Surfaces
Abstract
The design of supersonic/hypersonic flight vehicles requires the integration of aerodynamics, thermodynamics, structural mechanics, propulsion systems, and flight dynamics, among other areas. Interactions between a supersonic/hypersonic gas flow and solid surfaces of a flight vehicle are recognized as a central problem in the design of high-speed vehicles. By leveraging the technical strength of the PI, Dr. Thomas Ward, in theoretical hypersonic boundary layer modelling and computational fluid dynamics, and the expertise of the collaborator/mentor, Dr. Hui Hu, in experimental aerodynamics and advanced flow diagnostics, we proposed to conduct research that integrates theory, computation and experiments to examine the aero-thermo-elastic interactions of supersonic/hypersonic flows and solid surfaces, and to characterize the responses of the solid surfaces to the resultant high thermal and stress loads. In this research program, we proposed to develop a new class of molecule-based flow diagnostic techniques (e.g., molecular tagging velocimetry/thermometry and pressure/temperature sensitive painting techniques) to achieve nonintrusive, quantitative measurements multiple flow properties (e.g., velocity, temperature and pressure) of supersonic/hypersonic flows. Based on modern Prandtl boundary layer theories (i.e., shock-layer and triple-deck analyses), a set of low-order models for supersonic/hypersonic boundary layer simulations with minimal computational cost will also be developed in order to predict weak/strong fluid-thermal-solid interactions pertinent to supersonic/hypersonic flights. The proposed research will significantly advance the state-of-the-art in aero-thermo-elastic analysis of supersonic/hypersonic flows and to improve understanding of fluid-thermal-structural interactions in supersonic/hypersonic flights. Therefore, the proposed efforts align very well with the Air Force mission and broader societal interest in the development of next generation supersonic/hypersonic vehicles.
