Turbulent flow is a type of fluid motion characterized by chaotic changes in pressure and flow velocity, often occurring at high velocities or with large obstacles. It contrasts with laminar flow, where fluid moves in parallel layers, and is crucial in fields such as aerodynamics and hydrodynamics for predicting fluid behavior and designing efficient systems.
