【摘要】 着重考虑纳米颗粒电性质对气泡附近颗粒动力学的影响。在传统的郎之万方程的基础上,添加了颗粒气泡的静电作用以及颗粒扩散电层变形的效应。对典型的运动状态进行深入的探讨,分别考察了低电势颗粒和高电势颗粒在气泡附近的运动状态,得到部分情况下具有普遍意义的动力学表达式。结论具有定性分析纳米颗粒与气泡碰撞的意义。更多还原

【Abstract】 Conducted an investigation on particle dynamic characteristics near bubble in nanofluids.The electrical properties of particles and bubbles have strong effects on particle-bubble collision and make the collision process differ from Brown motion for micro-particles.The electrostatic interaction energy and distortion of particle diffusion layer was introduced to get modified Langevin equation,and expression of particle movement for certain cases was derived.更多还原
