High-speed flow is a research area that focuses on the study of fluid dynamics at velocities close to or exceeding the speed of sound. This field is relevant in various applications such as aerospace engineering, gas dynamics, and high-speed propulsion systems. Researchers in high-speed flow study the behavior of fluids at high velocities, including shock waves, boundary layers, and compressibility effects. Understanding high-speed flow is important for developing efficient and safe designs for supersonic and hypersonic vehicles, as well as for improving the performance of existing technologies.
