A theoretical and experimental study of thermal plumes arising from finite heat sources is conducted. The research is aimed at advancing fundamental understanding, but the study has significant relevance in the environmental and electronic cooling technologies. In the case of a horizontal, upward-facing heated disk, the preliminary study indicates the importance of the developed thermal plume and the near-disk flow. The near-disk region can be characterized by a boundary layer analysis which connects with the analysis of the entrainment flow above the boundary layer. The study predicts analytically the local and averaged disk and plume analyses. The theoretical study is supported by three-dimensional full field temperature data obtained using holographic interferometry and thermocouple probes.

对有限热源产生的热羽流进行了理论和实验研究。这项研究的目的是促进对基础知识的理解，但这项研究在环境和电子冷却技术方面具有重要意义。在水平向上加热圆盘的情况下，初步研究表明了发展的热羽和近圆盘流动的重要性。近盘区域可以用边界层分析来表征，边界层分析与边界层上方卷吸流动的分析相结合。这项研究对当地和平均的圆盘和羽流分析进行了分析预测。理论研究得到了用全息干涉法和热电偶探头获得的三维全场温度数据的支持。
