| 摘 要： | This experiment is to study the special resistant induced by the high-speed evaporation surrounding the moving high-temperature particles. An observable equipment was designed, in which the first 11 experiments were performed by pouring one or several Zirconia spheres with various high-temperature and a diameter of 3-10mm into a water pool. The particles falling-down speeds were recorded by high-speed photographic instrumentation,and pressures and water temperatures were measured. A comparison between the experiments with cold and hot spheres respectively, employing three different sphere types each, was presented. The experimental data, com-pared with the theory of the evaporation drag model, are nearly identical.

| Abstract: | This experiment is to study the special resistant induced by the high speed evaporation surrounding the moving high temperature particles. An observable equipment was designed, in which the first 11 experiments were performed by pouring one or several Zirconia spheres with various high temperature and a diameter of 3~10 mm into a water pool. The particles falling down speeds were recorded by high speed photographic instrumentation, and pressures and water temperatures were measured. A comparison between the experiments with cold and hot spheres respectively, employing three different sphere types each, was presented. The experimental data, compared with the theory of the evaporation drag model, are nearly identical. |
