Special Issue Information

Dear Colleagues,

High-speed wall-bounded flows play a key role in aerospace applications, such as unmanned supersonic/hypersonic vehicles, scramjets, advanced space aircraft, and propulsion systems. The development of an extremely thin boundary layer plus the abrupt changes in the wall on the freestream flow parameters result in high momentum/thermal gradients with a significant impact on the transport phenomena. Hypersonic flows are energetic and result in regions of high temperature, causing internal energy excitation and aerothermodynamics problems. Therefore, the acquired knowledge of the physics behind high-speed boundary layers can lead to the development of more efficient turbulence modeling or control techniques for aerodynamic heating. The “rejuvenation” of high-speed aerodynamics, space exploration, and military technology advances has introduced a pressing responsibility on the computational fluid dynamics (CFD) community to achieve high fidelity results in higher Reynolds and Mach numbers and evermore complex geometries, not to mention the optimal design of thrust generation systems.

The Special Issue “High-Speed Aerodynamics and High Energy and Efficiency Aerospace Propulsion System: Modeling and Optimization” is focused on documenting innovative developments in the fields of high-speed fluid dynamics related to external and internal fluid flows for aerospace applications and basic research. Suggested topics include (but are not fixed):

  • Spatially developing turbulent boundary layer (SDTBL);
  • Jet in crossflow problem (JICF);
  • DNS/LES/RANS;
  • High-speed aerodynamics of vehicles;
  • Boundary layer transport phenomena;
  • Shock wave boundary layer interactions (SWBLIs);
  • Rarefied flows;
  • Propulsion system analysis;
  • Combustion modeling;
  • Parallel and GPU programming in CFD;
  • Coherent structure analysis.

High-speed global surface temperature distributions and heat flux measurements on the Initial Concept 3.X vehicle (IC3X) model were investigated at the UTSA Mach 7 wind tunnel, examining angles of attack of 0° and 5° at a freestream unit Reynolds number (Re) ~7 × 106 m−1. A ruthenium-based, fast-responding, temperature-sensitive paint (fast-TSP) prepared in-house was applied to a 7.1% scale model of the vehicle. Static calibration was performed to convert the intensity measurements into surface temperature values. The surface temperatures and derived heat flux fields conformed to the predicted trends, which was corroborated by Schlieren flow visualization. Notably, the average surface temperature variation was identified to range from 6 to 34 K at a 0° angle of attack and from 11 to 44 K at a 5° angle of attack, with the most pronounced gradient detected at the stagnation point. Additional measurements provided a detailed thermal assessment of the model, including estimations of the stagnation point heat flux, the convective heat transfer coefficient, and the modified Stanton number. Statistical and time series analyses of the data collected revealed the absence of prevailing unsteady phenomena, suggesting that the tested design geometry is well suited for hypersonic flight applications. These experimental outcomes not only shed light on the aerothermodynamics experienced during high-speed flight but also underscore the effectiveness of fast-TSP in capturing both quantitative and qualitative thermal data.
