| 摘 要： | 根据作者关于拉伐尔喷嘴中气粉流的数学模型，采用确定喷嘴临界截面的马赫数检验法，对不同形状拉伐尔喷嘴中气粉流的行为做了理论研究，数值计算表明，气体速度和粉粒速度均随曲粒半径的增大而增大，拉伐尔喷嘴的长度则随曲率半径的增大而减小。

| Abstract: | According to author's mathematical model describing the gas-particle flow behavior when passing through a Layal nozzle in combination with the Mach number checkout method to determine the critical cross-section of nozzle,the behavior of gas-particle in Layal nozzles of different configurations are calculated theoretically. Numerical calculation results show that the gas and particles velocities increase with the radius of curvature,and the length of Layal nozzle increases with decreased radius of curvature. |
