Spectral distribution of scattered light from a chemical relaxation system
Marques Júnior, Wilson; Kremer, Gilberto M.; Bianchi, M. Pandolfi; Soares, A. J.The aim of this work is to describe the light scattering spectra of a quaternary reacting gas mixture from the macroscopic field equations derived from the kinetic BGK-type model proposed by the authors in a previous paper. The study is developed in a hydrodynamic regime for which the system of the field equations of constituent number densities, momentum and temperature of the mixture is closed by the constitu...
From the transport coefficients of a relaxation kinetic model to harmonic wave ...
Kremer, Gilberto M.; Bianchi, M. Pandolfi; Soares, A. J.Special issue - International Conference on Transport Theory 2009 ; For a gas system of four constituents which experiences the bimolecular chemical reaction A1+A2=A3+A4, and in a regime close to the chemical equilibrium, the BGK-type model proposed by the authors in a previous paper is here considered with the aim of studying plane harmonic wave solutions to the system of the reactive field equations. The ...
First order kinetic approximation for a reactive gas mixture
Soares, A. J.; Bianchi, M. PandolfiA multicomponent reacting gas with an arbitrary number of chemical species and one reversible reaction is studied at a kinetic level in the frame of Discrete Velocity Models of the Boltzmann equation, with the main objective of deriving the "reactive" Navier Stokes equations of the model, and characterizing the dissipative terms related to shear viscosity, thermal conductivity and thermal diffusion. The closure...
Kinetic approach to transport properties of a reacting gas
Soares, A. J.; Bianchi, M. PandolfiA multicomponent reacting gas with reversible reactions is studied at a kinetic level with the main objective of deriving the reactive Navier-Stokes equations in dependence on the macroscopic variables, and characterizing the dissipative terms related to shear viscosity, heat conduction and thermal diffusion. A step-by-step procedure, which can be applied to a quite large variety of reactive flows, is proposed ...
