# The Navier-Stokes Equations

# Fluid Dynamics

Fluid dynamics is a field in science and engineering that describes the flow of fluids, i.e. liquids and gases, with many subfields such as aerodynamics and hydrodynamics. To solve problems in fluid dynamics, physical properties of the fluids such as velocity, pressure, density, and temperature are taken under consideration as functions of space and time. There are many practical…
