中文摘要：

重点研究的是水和乙醇在放置了强化元件的光滑铜表面上的池核沸腾传热性能。该强化元件对部分加热表面上方的空间进行限制,使液体存在的空间就被分为交替存在的受限空间和自由空间。本研究中所探讨的主要参数是热通量（13～400 kW/m2）和受限空间尺度（0.2 mm,0.5 mm,无限制结构）。实验结果表明,对水和乙醇而言,这样的强化元件都可获得良好的沸腾传热特性.可视化结果表明,几乎所有有效核化区域都在受限空间内,即使在高过热度下自由空间内也很少出现有效核化点。

英文摘要：

An experimental study of pool boiling on the modified copper enhanced structure,with the separate ordinary confined spaces and the open channels between the confined spaces structures was conducted with water and ethanol.The heat flux investigated in this study ranged with 13～400 kW/m~2 and confined space dimensions were specified at 0.15 mm,0.5 mm,no confined.The results show that the boihng performance of both water and ethanol can be enhanced on the plain surfaces covered with the enhanced structures.The visual observation indicated that most of the active nucleation sites emerged in the confined space covered by enhanced structures even at high superheat.
