| Abstract: |
| 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 150.8A— 2009 rain test. |
