| 摘 要： | 本文通过采用物理气相沉积法于TiO2纳米管阵列表面修饰一层聚四氟乙烯(PTFE)纳米颗粒,得到超疏水表面,并研究此超疏水纳米结构表面的池沸腾特性.研究表明,超疏水纳米结构表面沸腾特性类似于膜沸腾,沸腾工质难以浸润该表面,其沸腾传热系数及临界热流密度均较低.分析表明,固液处于Cassie-Baxter接触状态,纳米结构表...

| Abstract: | In this work,pool boiling heat transfer of superhydrophobic nanostructured interface is investigated on the teflon(PTFE) nanoparticles decorated TiO_2 nanotube arrays(TNTAs) interface. The PTFE nanoparticles layer on the TNTAs was prepared by physical vapor deposition method.The pool boiling performance of the superhydrophobic interface was similar to the film boiling.During the pool boiling process,the water can hardly soak the superhydrophobic interface,and the boiling heat transfer coefficient and the cr... |
