ON THE VISCOSITY OF NATURAL GAS
The existing measuremenJs of the viscosity of gaseous systems can be extended if use is made of statistical mechanics. In this work, we confine ourselves to the measurements of the viscosity of multicomponent mixtures of low-density gases. The method is applied to one sample of natural gas.
متن کاملVISCOSITY COEFFICIENTS OF THE A-PHASE OF SUPERFLUID He AT LOW TEMPERATURES
It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

متن کاملViscosity of a Lattice Gas
The shear viscosity of a lattice gas can be derived in th e Boltzmann approximat ion from a straightfor ward analysis of th e numerical algorithm. Thi s computat ion is presented first in the case of the Friech-Hasslacher-Pome au two-dimensional triangular lattice. It is then generalized to a regular lat t ice of arbitrary dimension, shape, and collision rules with appropriate symmetries . The ...
متن کاملShear viscosity of pion gas
Shear viscosity η is one of transport coefficients in fluid dynamics, which characterizes how viscous the system is in the presence of flow gradient [1]. Since, in general, shear viscosity is inversely proportional to scattering cross-section, strongly interacting systems have smaller viscosity than weakly interacting ones. Recently a universal minimum bound for the ratio of η to entropy densit...
