随着电子元件高性能化和小型化的发展,纳米通道内工质的流动传热问题受到了更多的关注.本文采用分子动力学模拟方法,模拟了300,325,350 K的纳米通道中流体的流动传热情况,工质为水,水中不凝性气体用氩气代替.结果表明:流动过程中,氩原子形成高势能团簇,随着温度升高,流体势能上升,团簇逐渐减小或消失;少量气体原子能够促进流动,而较多氩气会导致通道中心区域形成较大气体团簇而阻碍流动,同时,被加热的工质能显著减小流动阻力系数;近壁面区域流体温度高于中心区域,团簇内部原子活动更加剧烈,平均分子动能更大,温度更高;水的氢键结构可以促进纳米通道内的传热,氩原子会影响氢键数量,高温会破坏水分子形成的氢键网络,使努塞尔数下降.本研究分析了不凝性气体影响下微通道内水分子流动传热的机理,为电子设备的强化传热提供了理论指导.

混合润湿性对固/液相互作用有显著影响,因此对提高相变过程中的传热速率有积极作用.采用分子动力学模拟方法研究了柱状纳米结构表面混合润湿性对池沸腾传热的影响.分析了混合润湿性和纳米结构柱高对液体起始沸腾时间和温度的影响及其机理.结果表明,疏水比例和柱高会影响爆沸的起始温度和时间.与纯亲水壁相比,增加疏水比改变了固液界面性质,可以降低沸腾温度,更容易突破势能壁垒,使液体起始沸腾时间提前,并且随着疏水比的增加,不同柱高下的沸腾温度降低;当疏水比相同时,增加柱高扩大了混合润湿性的影响,也能降低沸腾起始温度并使液体起始沸腾时间提前.这为设计微纳粗糙结构和混合润湿表面以强化沸腾传热提供了思路.
