摘要:
通过实验研究与观察 ,首次提出并证明了微小空间粉末多孔薄层表面上几个不同的沸腾传热阶段 .与光滑表面上的沸腾有着本质的不同的是 ,多孔表面上临界沸腾只有在多孔薄层表面以上形成纯蒸汽膜时才能发生 ,而临界沸腾热流比光滑表面高 1～ 2倍 .综合实验结果得出多孔薄层表面上临界沸腾热流计算关联式 .
Abstract:
The t heories about different boiling stag es on micro por ous sur face are put forward first time and tested by ex periment ( by using video) in this paper. Being qualitatively different from boiling on smooth surface, the temperature of critical boiling on micro porous surface only takes place w hen a pure vapor film forms abov e the porous surface, critical heat flux on micr o porous surface is 1~ 2 times hig her than that on plain sur face. A calculating equation o f cr itical heat flux on t he porous surface is gotten on the basis of the ex periment.
