- 摘要:
- 在农业应用中,饲草的干燥分离经常会用到旋风分离器,由于饲草颗粒的运动方向及速度都会对它的轨迹产生影响,进而影响分离及干燥的效率。为此,根据旋风分离器的工作原理,通过介绍离散相颗粒模型,气固两相流中固体颗粒的受力分析,最后基于fluent模拟,分析偏移速度对饲草颗粒运动轨迹的影响。结果表明偏移速度的改变对稀相固体颗粒运行轨迹的影响不大。模拟的结果起到避免陷入研究误区的作用,对农业中饲草的干燥及分离具有一定的指导和借鉴意义。
- Abstract:
- In the agriculture application,drying separation of forage grass often uses cyclone separator.As a result of forage grass particles motion direction and speed will have influence on its trajectory,and further influence the efficiency of separation and drying.Therefore, according to the operating principle of the cyclone separator,the discrete particle model was introduced,the stress of solid particles in gas-solid two phase flow was analyzed, finally,based on the Fluent simulation,the influence of migration velocity on forage grass particle trajectory was analyzed.The results showed that the change of migration velocity has little effect on dilute phase particle trajectory.The results of simulation could avoid the misunderstanding of the research,forage grass drying and separation has certain guidance and reference significance in the agriculture.
