| 摘 要： | 文中以空气为工质,对水平光管、横纹管、花瓣管在夹套间的强制对流传热进行了高压电场强化(EHD效应)实验研究,揭示了EHD在强化对流传热上的一些基本规律。实验结果表明,外加高压电场对强化对流传热有较好的综合效果,在Re=5000,电极电压为30 kV的实验条件下,花瓣管、横纹管和光管的最大强化率依次为2.76,1.75和1.36。根据光管的实验结果,对有、无电场作用下的压力波动进行了时间序列分析,得出了Lyapunov指数,并从动力学角度分析了EHD效应对强化传热的影响。

| Abstract: | An experiment was performed for the forced convective heat transfer of air through smooth tube,traverse corrugated tube and petal-shaped fin tube under direct current high voltage in annulus.Some convective heat transfer rules of electro-hydro-dynamics(EHD)enhancement were studied.The experiment results show that the direct current high voltage has favorable heat transfer effect on forced convective heat transfer.When Re is 5 000,the voltage is 30 kV,for the thimble experiment,the maximal intensifying rate ... |
