论文摘要
本文研究了借助自设计的云腔，研究了环境参数（例如湿度和湍流）的依赖性，以确定雨滴形成的条件。研究方法本质上是实验性和观察性的，在这种方法中，通过使用适当的替代品来重现大气现象。通过使用干冰冷却水蒸气的升温，以形成悬浮的水滴，并诱导较重的液滴降水，从而在盒子状的设置中创建微型液滴。实验导致产生沉淀的液滴，在腔室的底部发现，相对湿度为99-100％。悬浮的液滴用于研究诸如张力和湍流的液滴大小的变化等因素。发现高达14.4 m/s的湍流，液滴尺寸随着湍流的增加而增加，随着湍流的增加，发光度降低。还获得了液滴尺寸分布的高斯轮廓，低，中和高湍流速度的标准偏差分别为2.83、3.01和3.18。可以扩展实验以结合更高数量的变量，以包括更广泛的大气现象。
Present paper examines the dependency of ambient parameters such as humidity, and turbulence to determine the conditions on raindrop formation with the help of a self-designed cloud chamber. The research methods are experimental and observational in nature, where atmospheric phenomena are recreated through the usage of appropriate substitutes. Miniature droplets were created inside a box-like setup through the use of dry ice to cool the water vapor rising up, so as to create suspended water droplets, and to induce precipitation of heavier droplets. The experiment resulted in the creation of precipitated droplets, which were found at the base of the chamber at 99-100% relative humidity. The suspended droplets were used to study factors such as luminosity and variation of droplet sizes with turbulence. It was found that up to 14.4 m/s of turbulence, the droplet sizes increase with an increase in turbulence, with the luminosity decreasing with increase in turbulence. The gaussian profile of droplet size distribution has also been obtained, with a standard deviation of 2.83, 3.01 and 3.18 for low, medium and high turbulence speeds respectively. The experiment can be extended to incorporate a higher number of variables, so as to include a wider range of atmospheric phenomena.
