纳米流体液滴的耗散粒子动力学模拟

Dissipative particle dynamics simulation of nanoparticles droplet

采用在介观尺度下适用的耗散粒子动力学(dissipative particle dynamics,DPD)方法,对考虑静电力作用的纳米流体系统进行建模,研究了在纳米颗粒带电量和浓度影响下纳米流体液滴接触角的变化.通过对实验过程进行的数值模拟,得到了定性相同的结果.

Mesoscale dissipative particle dynamics was used to model a nanofluid system considering electrostatic interaction. The effects on the droplet static contact angle of the concentration and charge quantity of the nanoparticles were investigated. Computational results were qualitatively agreed with experiments.
