To study the escaping problem at the both side of Pneumatic Grasshopper Trapper in the capturing process and improve the suction trap rate, firstly, measure the flow field of Head-suck in Pneumatic Grasshopper Trapper.
为了深入地探讨草地蝗虫吸捕机在吸捕过程中蝗虫在吸嘴两侧逃逸的问题以及进一步提高机器的吸捕率,首先对草地蝗虫吸捕机吸嘴处的流场进行实验测量,然后在吸嘴流场分析中引入计算机模拟,利用Fluent软件中的RNG k?ε湍流模型对吸嘴流场进行数值模拟,模拟结果与实验结果之间的误差均在6%以下,证明该数值算法是可行的,为草地蝗虫吸捕机吸嘴的改进设计提供便利条件。
补充资料：土蝗
1.蝗虫的一类，形状略似飞蝗，分布地区很广。多分散在田间或草地上，吃植物。但不成群飞翔，也很少飞到较远的地区，危害性比飞蝗小。
