1. Turbulence model

The level of turbulence in a fluid can be defined using the Reynolds number: Re=LUν

with :

L
 : 
characteristic scale (diameter of an obstacle, for example)
U
 : 
characteristic speed (often the average fluid velocity)
ν
 : 
kinematic viscosity.

The higher the number, the more turbulent the fluid.

For a fixed geometry, a fluid...
