中文摘要：

本文利用可视化实验台对非均匀孔隙内加热铂丝上的沸腾核化和气泡动力学特性进行可视化观测,分类整理和对比分析了不同条件下的实验现象。实验表明,非均匀孔隙内加热丝上的沸腾核化具有空间区域性,气泡动力学特性包括界面传递、干涸与湿润过程在不同特征区域,如角缝区、稀疏区和密集区呈现出各自特征。

英文摘要：

A visual experimental investigation was conducted to observe dynamic behavior of boiling on a heating wire embedded in non-uniform bead-packed pores. The experiments show that boiling nucleation was closely dependent upon the pore structure and dvnamic bubble behavior including interfacial transport, dryout/rewetting process were characterized in different regions, or narrow corner, sparse pore and/or main pore zone and tightly packed-zone, respectively.
