【摘要】：实践十号蒸发对流实验以微重力环境中的蒸发相变流体界面过程为主要研究内容,利用空间微重力条件下浮力对流消失和热毛细对流起主导作用的特殊环境,实验研究置于加热底板的蒸发液滴相变过程中表面蒸发与表面张力驱动对流的耦合机理.利用研制的空间蒸发对流装置完成了在轨工况的科学匹配实验,得到了不同工况(温度、液滴大小、加热底板材料)下蒸发液滴形貌和热流量、蒸发速率等变化规律.为后续空间实验结果的比对分析提供了前期结果.
[Abstract]:Practice No. 10 evaporation convection experiment focuses on the interfacial process of evaporative phase change fluid in microgravity environment, and makes use of the special environment in which buoyancy convection vanishes and thermocapillary convection plays a leading role under the condition of microgravity. The coupling mechanism between surface evaporation and surface tension driven convection during the phase transformation of evaporated droplets placed on the heated bottom plate was experimentally studied. The scientific matching experiment was completed using the developed space evaporative convection device. The morphology, heat flux and evaporation rate of evaporated droplets under different working conditions (temperature, droplet size, heating substrate material) were obtained, which provided preliminary results for the comparison and analysis of the results of subsequent space experiments.
