aerodynamics
n.n. the study of how air moves around objects and how that movement affects their speed and direction. It helps engineers design things like cars, planes, and sports equipment to move more easily through the air.
n. the branch of fluid dynamics concerned with the motion of air and other gases and the interaction of air with solid bodies moving through it.
The car's shape is designed for better aerodynamics.
Engineers spent years testing the new wing design to improve the plane's aerodynamics and fuel efficiency.
Advances in computational fluid dynamics have allowed designers to simulate complex aerodynamic forces without the need for expensive wind tunnel testing, significantly reducing the time required for vehicle development.
From aero- + dynamics. Compare French aérodynamique, German Aerodynamik, and Italian aerodinamica.
