Flow dynamics is a branch of fluid mechanics that focuses on the study of how fluids move and interact with solid boundaries. It involves the analysis of the behavior of fluids under various flow conditions, including both laminar and turbulent flow. Flow dynamics is important in fields such as engineering, biology, meteorology, and environmental science, as it helps scientists and researchers understand the movement and behavior of fluids in different systems. By studying flow dynamics, researchers can better predict and control the behavior of fluids in various applications, such as in the design of aircraft, vehicles, and industrial processes.
