| 摘 要： | 根据气粉流的质量，动量和能量守恒等基本定律，建立了描述了组合管中气粉流行为的数学模型，数值计算结果表明，粉粒终速随粉粒密度的增大或粉粒粒径的增大而减小，且随粉气化的增大而增大。

| Abstract: | According to the fundamental laws of conservation of mass .momentum and energy in gas-particle now, a mathematical model was developed to describe the behavior of gas-particle flow in a combinedduct. The numerical results of calculation show that the terminal particle velocity decreases with the increasein particle's density or size but increases with the ratio of the mass flow rate of particles to that of gas-particleflow. |
