Forced oscillations in simple and binary gas atmospheric models
… of the mutual diffusion of the components of a binary gas system, where he compared different equilibrium configurations. This statical treatment again ignores the damping effects on mass flow. D.G. Parkyn reduced the problem in idealised form to that of investigating the effect of a travelling …

A Lattice Boltzmann model for diffusion of binary gas mixtures
… of a Lattice Boltzmann (LB) model for a binary gas mixture. Specifically, channel flow driven by a density gradient with diffusion slip occurring at the wall is studied in depth. The first part of this thesis sets the foundation for the multi-component model used in the subsequent …

Bubble Dynamics and Dense Phase Composition in 2-D Binary Gas-Solid Fluidized Bed
Gas-solid bubbling fluidized bed with binary particles is a potential candidate for performing the dry coal beneficiation process due to its advantages such as the ability to adjust separation density and the elimination of process water. A two-dimensional (2D) fluidized bed was used to study …

Binary gas adsorption on molecular sieves. Experimental data for the adsorption of oxygen, nitrogen and oxygen-nitrogen mixtures on five molecular sieve adsorbents at various temperatures and pressures and a comparison with theoretical models.
… apparatus, have been measured for each gas on each adsorbent at pressures up to 9 bar and for temperatures of 278.15,293.15 and 303.15 K. Curve fitting of the pure canponent isotherms has been attempted using the kinetic model of Gonzalez and Holland, the vacancy solution model, the …

Mass Transfer of Alkane Solvents-CO2-Heavy Oil Systems in the Absence and Presence of Porous Media Under Reservoir Conditions
… due to heat loss to over- and under-burdens, gas injection is considered to be an effective alternative. One of the major mechanisms associated with gas injection is the molecular diffusion of dissolved gas(es) which reduce the viscosity of heavy oil while inducing oil swelling. Physically, …

Nonlinear Acoustic Waves Generated by Surface Disturbances and Their Effect on Lower Thermospheric Composition
… stratified lower thermosphere often use single gas approximations with height-dependent physical properties (e.g. mean molecular weight, specific heats) that do not vary with time (fixed composition). This approximation is simpler and less computationally expensive than a true multi-fluid model, …

Studies of Mixing Processes in Gases and Effects on Combustion and Stability
… models of laminar mixing of initially separated gases are studied. Two models study the effects of the mixing dynamics on the chemical reactions between the gases. The third model studies the structure and stability of a laminar mixing layer in a binary gas. The three models are:</p> <p>1. Two …

Multiphysics Transport in Heterogeneous Media: from Pore-Scale Modeling to Deep Learning
… in porous media, the storage and recovery of gas from ultra-tight shale formations are investigated at the single-pore scale using molecular dynamics simulations. In the single-component gas recovery, a super-diffusive scaling law was found for the gas production due to the strong gas …

Deterministic numerical simulation of the Boltzmann and kinetic model equations for classical and quantum dilute gases
… equations fail to describe the gas dynamics when the molecular mean free path is not negligible compared to the characteristic flow length. Instead, the Boltzmann equation is used to account for the non-continuum nature of the rarefied gas. Although many efforts have been made to …

Acoustic-Gravity Wave Propagation Based on Solutions to the Generalized Multi-component Transport Equations
