Fluid Mechanics

Fluid mechanics is the branch of physics and engineering that studies liquids and gases at rest and in motion, including the relationships among pressure, velocity, and forces.

Overview

Conservation of mass, momentum, and energy connects a fluid’s velocity, pressure, density, and temperature. In viscous flows, the Navier–Stokes equations describe the interplay of inertia, pressure, and viscosity. Laminar flow, turbulence, and boundary-layer separation reveal different patterns of motion, studied through analytical models, dimensionless quantities such as the Reynolds number, numerical simulation, and experiments.

Why it matters

Principles of fluid mechanics inform aerodynamic and hydraulic design, chemical processing, and meteorological modeling. They also provide quantitative frameworks for analyzing physiological transport mechanisms, including cardiovascular and pulmonary flows.
