果树喷雾用圆盘风扇三维气流速度场数值模拟与验证（Numerical Simulation and Experimental Verification of 3-D Air-velocity Field of Disk Fan Used in Orchard Sprayer）
果树 仿形喷雾 圆盘风扇
2010/12/29
为研究用于果树风送喷雾的圆盘风扇气流速度场分布特性，采用k-ε紊流模型和稳态求解方法，设置合适的边界条件，对单、双风扇不同出口风速的气流速度场进行三维稳态数值模拟和试验验证。结果表明，双风扇同时送风时，在离两风扇中心1~3m的范围内，中心区域的风速明显小于两边的风速，在3~5m的范围内中心区域的风速和两边的风速相差不大。模拟值与试验值对比表明变化趋势一致，二者的拟合直线决定系数R2分别为...

垄作喷药浅松除草机设计（Sprayer-cultivator-combined Weeder for Permanent Raised Bed System）
除草机 垄作 杂草防治
2009/8/11
针对甘肃河西走廊地区固定垄保护性耕作模式下，杂草种类繁多，多年生杂草根系粗大，春季较易复苏，不易喷杀，一年生杂草多为田旋藤蔓缠绕型，机械铲除不彻底等问题，设计了一台垄作喷药浅松除草机。该机采用化学喷药和机械浅松组合除草原理，由三段式可折叠机架、圆弧形防飘罩盖、化学喷药系统和机械浅松系统等组成。玉米苗期田间除草试验表明，机械浅松机构主要铲除玉米行间杂草，单独作业时杂草清除率为89.2%；化学喷药系统...
基于CFD的果园风送式喷雾机雾滴分布特性分析（CFD Simulation and Experimental Verification of Droplet Dispersion of Air-assisted Orchard Sprayer）
果园喷雾机 风送式CFD 模拟 雾滴 分布
2010/2/26
基于CFD技术建立了Hardi LB-255型果园风送式喷雾机雾滴沉积分布模型。根据实测的喷雾机相关参数，确定了二维流场的边界条件及模型参数，得到了约束条件下的雾滴沉积轨迹及不同层面上的沉积比率。设计了与模拟条件相同的验证试验，对模拟结果进行了验证分析。研究表明，在距风扇中心小于240cm的区域内，所建模型模拟结果能较准确描述雾滴沉积规律。 In order to investigate the ...
