Nonequilibrium effects of reactive flow based on gas kinetic theory
文献摘要：
How to accurately probe chemically reactive flows with essential thermodynamic nonequilibrium effects is an open issue.Via the Chapman-Enskog analysis,the local nonequilibrium particle velocity distribution function is derived from the gas kinetic theory.It is demonstrated theoretically and numerically that the distribution function depends on the physical quantities and derivatives,and is independent of the chemical reactions directly as the chemical time scale is longer than the molecular relaxation time.Based on the simulation results of the discrete Boltzmann model,the departure between equilibrium and nonequilibrium distribution functions is obtained and analyzed around the detonation wave.In addition,it has been verified for the first time that the kinetic moments calculated by summations of the discrete distribution functions are close to those calculated by integrals of their original forms.
