Dynamic viscosity
| Symbol | Definition | Unit |
| T refV | Dynamic viscosity reference temperature | °C |
| μref | Dynamic viscosity at T refV | kg/m/s |
| a | Dynamic viscosity first order temperature coefficient at T refV | K-1 |
| b | Dynamic viscosity second order temperature coefficient at T refV | K-2 |
Note: The model does not consider any variation of the gas dynamic
viscosity with the gas pressure.
