Wave Enhanced Heat and Mass Transfer

摘要-9708925张雪佳界面波在多相传热传质中起主要作用。一个重要的例子是在两相状态下运行的冰箱蒸发管的效率。最近的测试表明，它的效率是由于界面波的存在。有许多实验数据可以用来研究波浪对输运率的总体影响，但很少有数据可以用来探讨波浪统计和输运之间的耦合。这项工作将是对这种波的增强效应的平衡的理论、数值和实验研究，并将有助于更好地理解气/液和液/液流动。

Abstract - 9708925 Hsueh-Chia Chang Interfacial waves are known to play a major role in multi-phase heat and mass transfer. An important example is the efficiency of a refrigerator evaporator tube that operates in the two phase regime. Recent tests suggest that its efficiency is due to the presence of interfacial waves. Much experimental data exist with which to examine the gross effects of waves on transport rates but little data are available to probe the coupling between wave statistics and the transport. This work will be a balanced theoretical, numerical, and experimental study of the enhancing effects of such waves and will lead to a better understanding of gas/liquid and liquid/liquid flows.
