摘要
设计建立了高温颗粒下落冷液沸腾可视化实验装置 ,初次实验将一个或有限几个高温球形颗粒坠入低沸点的冷液中 ,利用高速摄像机记录其在冷液中的运动速度 ,以了解由周围冷液快速蒸发引起的作用在运动中高温颗粒上的特殊阻力 。
The content of this study was to design and build an observable experiment facility. The first series of experiments were performed by pouring an high temperature particle or six high temperature particles into a low saturated temperature liquid pool. The particles falling down speeds were recorded by high speed camera, so we can know the special resistant acting on the moving high temperature particles, which is induced by the high speed evaporation surrounding the particles. The study had experimentally verified the theory of evaporation drag model.
