摘　　要：本文基于相移干涉测量法高空间、时间分辨率定量可视化测量了近临界流体瞬态热对流边界层温度场。实验选取了两种具有不同临界距离的工况点,使用相移干涉测量方法获得了时间连续的全场相位信息,经过一系列处理后得到了高时间、空间分辨率的温度场可视化图像。研究获得了超临界传热过程中流体区域的全局温度场,定量分析了拟临界线附近不同工况点之间传热特征。In this paper,the temperature field of the transient thermal convective boundary layer of a near-critical fluid is measured quantitatively visualized with high spatial and temporal resolution based on phase-shift interferometry.Two working points with different critical distances were selected,and the time-continuous full-field phase information was obtained by using the phase-shift interferometry method.After a series of processing,a temperature field visualization image with high temporal and spatial resolution was obtained.The study obtained the global temperature field of the fluid region during the supercritical heat transfer process,and quantitatively analyzed the heat transfer characteristics between different operating points near the quasi-critical line.
