Hypersonic flow is often accompanied by phenomena such as shock waves and real gas effects, and its thermodynamic characteristics, transport characteristics, and energy transfer and conversion are very complicated. It involves additional instabilities, disturbance sources, and parametric influences that are not present at low speed. In general, hypersonic flow has four "high" characteristics: high-temperature, high-pressure, high-speed, and high-frequency, which brings great challenges to researchers. This special topic focuses on recent advances in the study of hypersonic flows.
