Fluid dynamics is a branch of physics devoted to studying the motion and properties of fluids—liquids and gases. It explores the behavior of fluids under various conditions, from the flow of rivers to the aerodynamics of aircraft. Central to fluid dynamics are principles such as the continuity equation, ensuring mass conservation, and the Navier-Stokes equations, fundamental to understanding fluid motion. Bernoulli’s principle reveals the relationship between fluid speed and pressure, while distinctions between laminar and turbulent flow define different fluid patterns. Widely applied in engineering and environmental sciences, fluid dynamics plays a critical role in optimizing systems and processes, contributing to advancements in technology, transportation, and environmental management.
