摘要：Super/hypersonic flow, mixing, and combustion processes are ubiquitous in next-generation aircraft and propulsion devices, for example, in the hypersonic aircraft and scramjet. Knowledge on physical mechanisms of high-speed compressible flow, mixing, and combustion has both important academic meaning and engineering value for developing effective flow control approaches, predicting accurately aerodynamic force and heat of aircraft, enhancing propulsion efficiency, and so forth. Experimental studies related to high-speed flows are very expensive and take time. Therefore, along with the development of computation technology, not only the computer hardware but also the calculation algorithm and software, numerical simulations play important roles in the study of super/hypersonic flow, mixing, and combustion processes. Numerical simulations can reduce research costs and provide the convenience in addition to discovering new flow phenomena, recognizing flow details, extending research topics, and so forth. In recent years, remarkable advances have been achieved in studies of transition prediction of super/hypersonic flow, supersonic mixing, heat transfer in high-speed flows, two-phase flows, and supersonic turbulent combustion by using the numerical simulation technology. In this special issue, we have invited some papers that address such issues.
