Special Issue Information

Dear Colleagues,

The research of high-speed processes in continuous media includes experimental and numerical studies in the field of designing aircraft, rockets, and landing vehicles, flow/flight control, as well as gas/plasma processes in combustion chambers, nozzles, electrical discharges, lasers, microwave pulses, and many others. Fast processes are characterized by complex shock–vortex interactions and the presence of large gradients of parameters due to the emerging shock waves, areas of shear deformations, and the possible development of various types of instabilities. The development of computer technology makes it possible to model such processes and predict their characteristics for subsequent experiments and technical solutions. High-speed optical diagnostic tools enable the highly accurate visualization of fast processes in various gas/plasma media. This Special Issue of Fluids aims to present the latest achievements in the numerical and experimental studies of high-speed processes in continuous media. Topics of interest include (but are not limited to) the following areas: the supersonic/hypersonic flow of gas and plasma, high-speed flow/flight control, shock waves, boundary layers, turbulence, chemically reacting flows, processes in plasma, combustion and explosion, ignition, vortices and vortex structures, heat flows, gas-dynamic and plasma instabilities, high-fidelity numerical methods, and the visualization of high-speed flows.

Modern software systems have implemented calculation techniques that allow numerical modeling of the icing of various aerodynamic objects and show themselves well when modeling the icing of objects at subsonic speeds. This paper describes a technique that is used to solve the problem of icing the profile of a NASA SC (2)-0714 airfoil streamlined by a supersonic gas stream. A feature of modeling this class of problems is the consideration of factors that arise when moving at high speeds: at supersonic flight speed, aerodynamic heating of the surface above 0 °C is observed, which is accompanied by a high intensity of impinging supercooled water droplets on this surface. The results of the numerical solution of the NASA SC (2)-0714 airfoil icing problem showed that even at a positive airfoil surface temperature, ice shapes can grow at the leading edge due to intense deposition of supercooled droplets.
