Large Eddy Simulation
The behaviour of fluids can be described by the well-known mathematical model known as the Navier-Stokes equations. The original equations include formulations for the conservation of momentum, energy and mass, therefore leading to three momentum equations, one energy equation and one continuity equation. The form presented below is a simplification of these equations for incompressible flows and a constant viscosity. For a detailed derivation of the Navier-Stokes equations as well as the simplifications applied for incompressibility, many textbooks on fluid dynamics are available, eg. ,  or .
