在这项研究中，进行了一系列的实验，以澄清空间限制的饱和沸腾传热现象的影响的结果报告。通过实验研究发现，在狭窄空间内的饱和沸腾传热中，除了孤立气泡区外，还存在一个特性明显不同的合并气泡区，其传热特性已被许多研究者所证实。本研究的主要目的是检测并验证聚并气泡区的传热特性。本文的前半部分在实验的基础上，比较了聚并泡区和孤立泡区的各种特性，并提出了一种新的聚并泡区关联方程。在后半部分中，基于一个简单的非稳态热传导模型进行了理论分析，并对相关方程进行了验证。
In this study, the results of a series of experiments conducted to clarify the space restriction effect on the saturated boiling heat-transfer phenomena are reported. Through the experimental study, it was detected that the saturated boiling heat-transfer in a narrow space there is a coalesced bubble region having remarkably different characteristics beside the isolated bubble region, the heat-transfer characteristics of which have already been confirmed by many researchers. The main purpose of this study is to detect and prove the heat-transfer characteristics of the coalesced bubble region. In the first half of this study, various characteristics of the coalesced bubble region and that of the isolated bubble region are compared, based on experimental findings, and coincidently, a new type of correlating equation for the coalesced bubble region is proposed. In the last half, a theoretical analysis based on a simple unsteadystate thermal conduction model is described, and the verification to the correlating equation is demonstrated.
