摘要
本文从有风时水滴运动受力分析入手,运用牛顿第二定理,导出了有风时的水滴运动方程并研究了其解法。通过同实测结果比较,证明计算模型具有一定精度。本文还分析了风对喷头射程的影响,结果表明:有风时喷头射程的相对变化率与风速呈直线相关,相关直线的斜率为风向及工作压力的函数。
On the basis of analyzing the moving of droplet under the wind force, a motion equation of droplet under wind condition and a method to solve this equation are de-veloped. It is proved that the equation has a good accuracy by comparing with the measured dala. In this paper, the effect of wind on the spray distance of nozzle is analysed also. The results indicate that there is a linear relation, the slope of which is a function of wind djrection and working pressure, between relative variation of spray distance and wind speed.
