New Method for Computing Viscosity: The Davidson Viscosity Model
For users of the Liquid & Gas Properties Module, COMSOL Multiphysics® version 6.0 brings a new Davidson model for computing viscosity in multicomponent mixtures based on the different components' contributions to the momentum of a gas in the system. The only data required for computing viscosity in the Davidson model are the molecular weights and the viscosities of the pure components at the given temperature and pressure. The Davidson model is computationally efficient and is as accurate as the best available models for estimating the viscosity of binary gas mixtures.
