Aerodynamics as a research area investigates the behavior of gases, primarily air, and the forces and flow phenomena arising when bodies move through them or when gas flows around stationary objects. It encompasses theoretical, computational, and experimental study of flow regimes (incompressible, compressible, transonic, supersonic, hypersonic), boundary layers, turbulence, flow separation, and aerodynamic forces and moments (lift, drag, pitching, rolling, yawing). The field develops and applies governing equations (e.g., Navier–Stokes, Euler), turbulence models, and numerical methods (CFD), as well as wind-tunnel and flight-testing techniques, to optimize performance, stability, control, and efficiency of vehicles and structures interacting with fluid flows.
Professional cycling teams can reduce air drag for their protected rider by up to 76% by adopting specific formations different from the traditional single paceline, according to new research from Heriot-Watt University in ...
