Recent research revealed the orientation-dependent propulsion of a cone-shaped colloidal particle that is exposed to a planar traveling ultrasound wave. Here, we extend the previous research by considering nano- and microcones with different aspect ratios and studying how the propulsion of a particle depends on its orientation and aspect ratio. We also study how the orientation-averaged propulsion of a cone-shaped particle, which corresponds to an isotropic ultrasound field, depends on its aspect ratio and identify an aspect ratio of 1/2 where the orientation-averaged propulsion is particularly strong. To make our simulation results easier reusable for follow-up research, we provide a corresponding simple analytic representation.
最近的研究揭示了一个暴露于平面行波超声的锥形胶体粒子的取向依赖推进。在这里，我们通过考虑具有不同纵横比的纳米和微米锥，并研究粒子的推进如何取决于其取向和纵横比，扩展了先前的研究。我们还研究了对应于各向同性超声场的锥形粒子的取向平均推进如何取决于其纵横比，并确定了一个纵横比为1/2时取向平均推进特别强的情况。为了使我们的模拟结果更便于后续研究重复使用，我们提供了一个相应的简单解析表达式。
