| 摘 要： | 对水平表面上小直径颗粒床的饱和池沸腾传热做了实验研究,发现热滞后特性获得了重大的改善,使温度过头现象可以消除,因而这种方法可能用以改进微电子元件的冷却。但沸腾传热在高热流下比平板时明显恶化。

| Abstract: | Experimental study was performed to investigate the holing transfer in liquid saturated porous bed.The incipient boiling chara-acteristics were exmined in detail.It is found that the boiling hysteresis may be well eliminated in the liquid saturated porous bed.However,deterioration of boiling heat transfer at high heat flux was observed. |

| Keywords: | pool boiling porous bed hysteresis critical heat flux |
