👉 Fluid dynamics is the branch of physics that studies the behavior and properties of fluids, such as liquids and gases. It involves understanding how these substances flow, deform, and interact with their surroundings under various forces, including gravity, pressure, and surface tension. Key principles include the conservation of mass (continuity equation), momentum (Navier-Stokes equations), and energy (energy equations). Fluid dynamics is crucial for explaining phenomena ranging from the flow of water in rivers and oceans to the movement of air in the atmosphere and the behavior of blood in the human body, making it fundamental to fields like engineering, meteorology, and biology.
