9.1     The Theory of the Fluid Flow Module

The implementation of the internal Fluid Flow Module is based on the conservation of mass, momentum and energy laws.

Fluid Flow Module in QuickWave uses equations for incompressible flow in Cartesian coordinate system.

The physical process of fluid flow implemented in QuickWave is described with the following formulae:

Equations for conservation of mass:

The Navier-Stokes equations for conservation of linear momentum:

  +

  +

  + +

Equations for conservation of energy:

  =

F =

Additionally Poisson's equation is applied:

(+ (+(+2 )+2 )+ 2))]
