Calculation of the dispersion of a compressed volume of a gas suspension

Numerical Simulation of Shock Wave Propagation n a Mixture of a Gas and Solid Particles

“…The flow in the shock wave (SW) propagating through such a mixture was described in many papers (see, e.g., [1,[9][10][11][12]). We assume that a quiescent mixture characterized by undisturbed flow parameters (ρ 10 , ρ 20 , u 10 = u 20 = 0, e 10 , e 20 , and p 0 ) is located in front of the SW.…”

Scattering of a compressed stratified concentrated mixture

“…This value is substantially lower than that in the case of scattering of a pure gas mixture (627 m/sec). Note that SW attenuation caused by scattering of a concentrated mixture of a gas and solid particles, as compared to the flow arising during scattering of a pure gas, was previously observed in our computations for low concentrations of particles [3][4][5].…”

“…The wave dynamics of the problem was described in [1,[3][4][5] within the framework of a mathematical model of a gas suspension with identical and then different velocities and temperatures and with a common value of pressure in the mixture, equal to the gas pressure. The criterion for CW origination was indicated in those papers.…”

Interaction of a normally incident shock wave with a porous material layer on a solid wall

“…showed that the model ensures a satisfactory description of the behavior of pressure in the shock-wave front, the pressure in the compression wave, and the delay time. This problem was solved previously within the framework of the nonequilibrium (in terms of velocities and temperatures) approach with the total pressure of the mixture equal to the gas pressure [7] with the use of the equation of state of a quasi-gas. The structure of the expansion wave propagating into the pure gas was analyzed, and its decay characteristics were quantified.…”
