The SI unit of dynamic viscosity (Greek symbol: ) is the pascal-second (), which is identical to .
The dynamic viscosity is related to the kinematic viscosity by
For the use in CFD, dynamic viscosity can be defined by different ways:
- as a constant
- as a function of temperature (e.g. piecewise-linear, piecewise-polynomial, polynomial, by Sutherland's law or by the Power law)
- by using Kinetic Theory
- by non-Newtonian models
