文摘:研究水蒸汽凝华结霜过程在冷壁上形成的霜层的导热系数,依据随机管子多孔介质霜层模型,假设霜层是由孔隙空间与冰晶骨架构成的多孔介质,其中孔隙空间由随机毛细管及连接管子的接头形成,湿空气中的水蒸汽在霜层的孔隙空间中扩散输运并凝华结霜,根据传热传质学理论,导出霜层导热系数关系式。 - The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie , the thickness , the temperature and the supersaturation with respect to ice of the nucleation layer ) . this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water , the density of the supersaturation of the vapor with respect to ice . simultaneously , the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude , and elicits the proper seeding altitude of the catalyst
以此解为依据,得出了不同均流时,人工引入冰核在核化层存留时间,再以此时间作为人工冰核凝华增长时间,求出不同的云宏微观背景(如核化层厚度、温度、冰面过饱和度等)下的冰晶谱分布,经和实际资料比对符合相当好。进而求出核化层中不同过冷水量、冰面过饱和水汽密度下云核化层可允许的催化用量。同时讨论了不同升速,不同高度引入人工冰核时对其存留时间的影响。 - If the cold plate temperature is higher than a certain critical value , for instance , - 12 c under our observed experimental conditions , the higher the air relative humidity is , the bigger the water droplets concreting on the cold plate , and the later the water droplets froze . however , if the cold plate temperature is lower than a certain critical value , the influence of air relative humidity on the frozen time of water droplets was not observed . if the cold plate temperature is higher than a certain critical value , for example , - 20 c under our observed experimental conditions , frost deposition is through condensation , or condensation frosting
