Turbulent flow is a type of fluid movement characterized by chaotic and irregular changes in pressure and velocity. In this flow, the fluid particles move in various directions, creating eddies and swirls. This behavior contrasts with laminar flow, where fluid moves in smooth, parallel layers. Turbulent flow is commonly observed in rivers, air currents, and around objects like airplanes and cars. Factors such as fluid velocity, viscosity, and the size of the object can influence whether flow is turbulent. When the flow speed exceeds a certain threshold, known as the Reynolds number, turbulence typically occurs. Understanding turbulent flow is essential in fields like engineering and meteorology.
