摘要
文章以烟丝群为研究对象对其在水平管道的运动方程进行分析,推导出时间、空间模式下的无因次方程;在初始速度为零的条件下,摩擦系数越大,烟丝群最终稳定速度越小,加速时间和加速距离也越小,悬浮速度对烟丝群最终速度影响不大。结果对系统的优化和运行有指导意义。
The motion equation and mathematical model of cut tobacco in horizontal pipe were analyzed in this article, the dimensionless equation on space and time pattern was deived. On the condition of zero initial velocity, the final stable velosity of cut tobacco decreas while friction coefficient increase; suspention velocity has little influence on it. The result has guiding significance for optimizing and operation of the system.
