The Boussinesq Approximation simplifies the Navier-Stokes equations for fluid flow by assuming that density variations are negligible except where they appear in buoyancy terms, making it useful for modeling incompressible flows with small temperature differences. This approximation is particularly valuable in geophysical and environmental fluid dynamics, such as oceanography and atmospheric science, where it helps to model the effects of buoyancy-driven flows without solving the full compressible equations.

The Navier-Stokes Equations are a set of nonlinear partial differential equations that describe the motion of fluid substances such as liquids and gases. They are fundamental to fluid dynamics and are used to model weather patterns, ocean currents, and airflow around wings, among other applications.

Navier-Stokes Equations

Fluid flow is the movement of liquid or gas particles in response to forces such as pressure differences, gravity, and external fields, characterized by velocity, pressure, and density variations. Understanding fluid flow is crucial in numerous applications, from engineering systems like pipelines and aircraft to natural phenomena like ocean currents and atmospheric circulation.
