AbstractA developed momentum transfer coefficient based on Wen’s 1966 model was proposed, in which the two threshold values were used to keep the continuous particle porosity function. A second-order moment gas–particle two-fluid turbulent model that coupled this coefficient, was established to model and simulate the particle horizontal channel flows. An improved Reynolds stresses transport to close fluctuation velocities correlation between gas and particle phases was set to reveal the fully anisotropic characteristics of particle dispersions. The hydrodynamics of horizontal gas–particle turbulent flow was numerically simulated and validated by experimental measurement with satisfied agreements. Distributions of particle Reynolds stresses are significantly affected by two-phase interactions, turbulent diffusions and particle collisions. Much wider size and flatter profiles distributions were obtained in terms of the horizontal and vertical root-means-square of particle velocities in comparison with Wen’s 1966 model.

In practice, one deals with gaseous mixtures more frequently than with a single gas. However, very few papers about the transport phenomena through a mixture of rarefied gases were published. The aim of this work is to present a general approach to calculations of mass, heat and momentum transfer through gaseous mixtures over the whole range of the gas rarefaction. Results on some classical problems such as slip coefficient, Poiseuille flow, Couette flow and heat transfer are given for a gaseous mixture. A comparison with results corresponding to a single gas is carried out. Such a comparison shows the peculiarities of the transport phenomena in mixtures.

We show the incompressible Navier–Stokes–Maxwell system with solenoidal Ohm's law can be derived from the two-fluid incompressible Navier–Stokes–Maxwell system when the momentum transfer coefficient tends to zero. The strategy is based on the decay and dissipative properties of the electromagnetic field.
