SOBER-SJ10是实践十号科学实验卫星19项科学实验载荷之一,通过局部过热在固定位置预定时刻激发产生气泡,并细致观测空间微重力条件下池沸腾现象中生长气泡热动力学过程与传热特征,来揭示沸腾气泡底部细观流动以及传热特性。利用已完成的7次地面实验、1次在轨阶段空间实验以及3次留轨阶段补充实验相关数据,分析了不同过冷度下地面实验沸腾曲线,并通过对天地实验中的沸腾气泡行为及气泡底部加热面温度等结果的对比分析,探讨了微重力环境对相关过程的影响。 |

SOBER-SJ10 is one of the 19 scientific experimental payloads aboard SJ-10 satellite. By exciting a micro-bubble at fixed time and position using local overheating method, the thermal dynamics of the growing bubbles and heat transfer in pool boiling are observed and measured in order to reveal the local micro-flow and heat transfer mechanism underneath the bubbles in microgravity. Based on the data of 7 ground experiments, boiling curves under different subcooling in normal gravity were analyzed. Furthermore, 1 in-orbit space experiment and 3 additional in-orbit space experiments have been performed. The influence of gravity on boiling process was discussed by comparing bubble behaviors and temperature variation beneath the bubble in different gravity conditions. |
