Abstract One of the most important flow properties of liquid is its viscosity. In the present paper, two non-equilibrium methods, Poiseuille flow method and Couette flow method, are employed to measure the viscosity of many-body dissipative particle dynamics (MDPD) model. The results obtained by these two non-equilibrium methods are consistent with each other. Based on Poiseuille flow method, we obtain a map for the viscosity of MDPD model with different numerical parameters. Furthermore, the static wetting of microbubbles is investigated by a selected system from the map. The relationship between the contact angle of bubbles and the solid-liquid interaction is obtained, which can be helpful for further microfluidic research and applications based on microbubbles.

多体耗散粒子动力学模型微泡在平面上润湿的粘度测量和模拟

摘要 液体最重要的流动特性之一是其粘度。本文采用泊肃叶流法和库埃特流法两种非平衡法测量多体耗散粒子动力学(MDPD)模型的粘度。这两种非平衡方法得到的结果是一致的。基于泊肃叶流法，我们得到了不同数值参数下MDPD模型的粘度图。此外，微泡的静态润湿由图中选定的系统进行研究。获得了气泡接触角与固液相互作用的关系，有助于进一步基于微气泡的微流体研究和应用。
