两相爆轰波的松驰结构明显区别于均相爆轰，除需考虑化学反应的影响外还需考虑两相流效应。本文的理论分析表明，化学反应效应和两相流效应对爆轰波松驰区内某些参数变化的影响是一对矛盾因素，这使得松驰区内的参数分布呈较为复杂的形态，均相爆轰中这类分布曲线往往是单调变化的。根据作者提出的云雾和粉尘爆轰模型所进行的计算表明理论分析与计算结果所呈现的姿势一致。文中还讨论了两相爆轰的C-J条件，Rayleigh方程和Hugonior方程，并根据计算绘制了Rayleigh曲线和Hugoniot曲线，这从另一侧面反映了两相爆轰波松驰结构的特征。

激波作用下，悬浮液谪在高温、高压和高速气流中变形、蒸发、剥离甚至破碎。雾化燃料经过一段延迟时间后点火燃烧释放出大量的能量。这些能量由局部爆炸波所携带，通过碰撞传递给引导激波。从而使气云爆轰波自持。文中提出的气云爆轰的一维模型考虑了上述基本过程，并从理论上推导了点火面和a面的判据。通过计算，文中讨论了气云爆轰的松弛结构和影响廿爆速的因素，爆速的计算值与实验值基本相符。

The propagation of a flame is investigated experimentally and theoretically for a large, horizontal combustion tube containing a mixture of air and aluminum powder with pre-existing turbulence. One end of the tube is closed and the other is connected to a large dump-tank. Twenty dispersion systems are used on the tube to produce a uniform suspension of aluminum dust in the tube with a mean diameter of 6mm. The characteristics of a flame front from the ignitors at the closed end are measured using photodiodes and the development of pressure is monitored by transducers. Experimental results revealed the entire process of an accelerating flame and the development of shock waves. A set of conservation equations for two-phase turbulent combustion flow is derived, using the two-fluid model, k-3 model, Hinze-Tchen model and EBU-Arrhenius model for turbulent combustion. The SIMPLE scheme usually applied to the homogeneous turbulent combustion is extended to fit this two-phase, reactive behavior. The results of calculations show the positive feedback coupling among combustion, expansion and turbulence during flame propagation. Computed and measured results are generally in good agreement.

Self-sustaining detonation along a combustible dust deposit on a bottom wall have been investigated experimentally and theoreticall. Experiments were conducted in a square cross-section tube. Three kinds of particles with a mean dianneter of 15μm were used; AL, RDX, and HMX. Sharp-shadow photographs were taken by means of a spectial optical system and shock-wave veloeties were measured by pressore transducers. It has been shown that the steady-state ditonation velocity is independent with initial shock wave strengths. An analytical model has been developed to describe the two-dimensional structure of dust-film detonations. A set of equations for the twe-phase turbulent-reaction boundary layer considering the particle ingestion and the interphase transfers and a general Chapman-Jouguet condition were derived. The Lees-Dorodnytzin transformation usually applied to the compressibie boundary layer has been extended to fit the two-phase reacting case, and the numerical siulations have been performed by applying a Box method and an improved particle source in cell (PSIC) method. Which shows that the structure of the boundary layer behind the shock fornt consists of an inducton zone, a reaction, and a diffusion zone. Computed and measured results are in reasonable agreement.

许多因燃烧导致的爆炸事故都与空间局部受限有关，例如管壁和管内障碍物可使火焰自行加速，并导致爆炸。基于湍流模型和EBU-Arrhenius燃烧模型，利用IMPLE格式对甲烷-空气混合物在管内燃烧时，因障碍物的作用而发生的爆炸现象进行了三维空间的数值模拟。计算结果描述了火焰加速和激波生成的过程。
