*FLUID CONSTANTS

Keyword type: model definition, material

With this option the specific heat at constant pressure and the dynamic viscosity of a gas or liquid can be defined. These properties are required for fluid dynamic network calculations. They can be temperature dependent.


First line:

Following line:

Repeat this line if needed to define complete temperature dependence.

Example:

*FLUID CONSTANTS
1.032E9,71.1E-13,100.

defines the specific heat and dynamic viscosity for air at 100 $ K$ in a unit system using N, mm, s and K: $ c_p=1.032 \times 10^9$   mm$ ^2/$s$ ^2$   K and $ \mu = 71.1 \times 10^{-13}$   N   s$ /$   mm$ ^2$.
