3D simulations reveal disturbances at hypersonic speeds, flow patterns create challenges

Researchers at the University of Illinois Urbana-Champaign conducted 3D simulations of hypersonic flow around cone-shaped models using supercomputers. They discovered unexpected disturbances and breaks in flow patterns at Mach 16, absent at lower speeds. This insight into complex hypersonic interactions could improve vehicle designs and safety. The team used advanced computational methods to track billions of air molecules and simulate their collisions, offering new understanding of flow behavior at extreme speeds.
