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 a random manner, creating eddies and swirls. This behavior typically occurs at high velocities or with large obstacles in the fluid's path, making it difficult to predict the flow patterns. In contrast to laminar flow, where fluid moves in smooth layers, turbulent flow is more complex and can enhance mixing and energy transfer. It is commonly observed in natural systems, such as rivers and oceans, as well as in engineering applications like pipes and aircraft design.
