*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:

• *FLUID CONSTANTS

Following line:

• Specific heat at constant pressure.
• Dynamic viscosity.
• Temperature.

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$^2$.
