摘要
对自然界中云滴到雨滴的转化和降雨的形成过程进行了阐述,同时对降雨过程中雨滴的形状、直径、降雨强度、终速度等的物性特点进行了分析。重点探讨了人工模拟降雨试验方法中关于雨滴直径0.5-4.5 mm、雨滴终速度9 m/s、行程、风速18 m/s等指标要求在实际试验中涉及的部分相关问题,基于对降雨过程和降雨引起的破坏机理的分析,结合淋雨设备原理和国内环境试验设备厂家现状,对现行GJB 150.8A—2009淋雨试验中的雨滴直径、雨滴终速度提出了补充完善的建议和意见。
In this paper,the conversion of cloud droplets to raindrops and the formation process of rainfall in nature are described.At the same time,the physical characteristics of raindrop shape,diameter,rainfall intensity,final velocity,etc.are analyzed.Focused on some of the relevant issues involved in the actual test of the artificial simulated rainfall test method about the raindrop diameter 0.5-4.5 mm,the final raindrop speed 9 m/s,the stroke,the wind speed 18 m/s and other indicators,based on the analysis of the destruction mechanism resulting from rainfall process,combined with the principle of rain shower equipment and the current status of domestic environmental test equipment manufacturers,this paper puts forward supplementary and perfect suggestions and opinions on the raindrop diameter and final velocity of raindrops in the current standard GJB 150.8 A—2009 rain test.
