Abstract

The paper numerically simulates the propagation of a shock wave through a gas suspension. The carrier medium is described as a viscous, compressible, heat-conducting gas. The mathematical model implements a continuum method for the dynamics of multiphase media, taking into account the interaction of the carrier medium and the dispersed phase. The mass transfer of disperse inclusions suspended in the gas, caused by the interaction of the shock wave with monodisperse gas suspensions and with gas suspensions having a multifractional composition, is modeled. Differences in the mass transfer of particles depending on the particle size are revealed. It is also found that the process of mass transfer of dispersed inclusions in a monodisperse gas suspension differs from a similar process for a fraction of a polydisperse gas suspension having the same particle size and the same volumetric content.

冲击波通过气体悬浮液时多分散性对分散相传质影响的数值研究

摘要

该论文对冲击波通过气体悬浮液的传播进行了数值模拟。承载介质被描述为粘性、可压缩、导热气体。该数学模型实现了多相介质动力学的连续介质方法，考虑了载体介质和分散相的相互作用。对悬浮在气体中的分散夹杂物的质量传递进行了建模，该质量传递是由冲击波与单分散气体悬浮液以及具有多分数组成的气体悬浮液的相互作用引起的。揭示了颗粒传质的差异取决于颗粒尺寸。还发现，单分散气体悬浮液中分散夹杂物的传质过程不同于具有相同颗粒尺寸和相同体积含量的多分散气体悬浮液部分的类似过程。
