The symmetric moderately dense reaction A+A⇌B+B is analyzed within the framework of Enskog’s equation by using the Chapman–Enskog method. For the last stage of a chemical reaction–where the affinity is considered a small quantity–the constitutive equations for the reaction rate...

A kinetic theory for a simple reversible reaction–characterized by a binary mixture of ideal gases whose constituents denoted by A and B undergo a reaction of the type A+A⇌B+B–is developed by considering the reactive collisions as inelastic ones. The geometry of the collision is taken into...

Enskog’s kinetic theory for a symmetric moderately dense reaction A+A⇌B+B is used to determine Fick’s and Fourier’s law. The transport coefficients of diffusion, thermal-diffusion rate and thermal conductivity are represented graphically for endothermic and exothermic reactions and are...

The aim of this paper is to study time-dependent problems like sound propagation and light scattering in binary mixtures undergoing a simple reversible symmetric reaction—of the type A+A⇌B+B—close to the final stage of the chemical reaction where the system tends to chemical equilibrium....

A kinetic theory is developed for binary mixtures of a monotomic gas (consisting of perfectly smooth, elastic, and rigid spherical particles) and a polyatomic gas (consisting of perfectly rough, elastic, and rigid spherical molecules). A macroscopic state of the mixture is characterized by 29...

A mixture of relativistic gases of non-disparate rest masses in a Schwarzschild metric is studied on the basis of a relativistic Boltzmann equation in the presence of gravitational fields. A BGK-type model equation of the collision operator of the Boltzmann equation is used in order to compute...

The aim of this work is to analyze the entropy, entropy flux and entropy rate of granular materials within the frameworks of the Boltzmann equation and continuum thermodynamics. It is shown that the entropy inequality for a granular gas that follows from the Boltzmann equation differs from the...

The light scattering spectra of dense monatomic gases are determined from a kinetic model of the Enskog equation in which the reference distribution function is a function of the gradients of velocity and temperature. A good agreement between the theoretical and experimental light scattering...
