【摘要】 采用分子动力学模拟比较了纳米通道中液体与固体相对静止、液体流动但界面无速度滑移以及液体流动且界面处存在速度滑移三种情况下的界面热阻,分析了流动和速度滑移对液固界面热阻的影响。模拟结果表明在低流速下流动和速度滑移对界面热阻的影响不显著,在较高流速下会导致界面热阻有10%左右的减小。更多还原

【Abstract】 Molecular dynamics simulations are carried out to investigate the influences of fluid flow and velocity slip on the solid-liquid interfacial thermal resistance.It is accomplished by comparing the interfacial thermal resistances under the conditions when the fluid is static or the fluid flows with/without boundary velocity slip.The simulation results demonstrate that the eff’ects of fluid flow and velocity slip on interfacial thermal resistance are negligible when the fluid flow is slow,and they will reduce the interfacial thermal resistance by about 10%with relatively high flow velocity.更多还原
