AI总结:

本文综述了非牛顿复杂流体(聚合物流体和颗粒悬浮液)液滴撞击固体表面的动力学研究进展,总结了最新实验、理论与计算成果,并指出了未来研究方向与挑战。

摘要:

流体液滴在固体基底上的撞击在许多工业涂覆和喷涂应用中引起了广泛关注,例如喷墨打印和农业农药喷雾。这些应用中使用的许多流体是非牛顿流体,即它们包含会强烈改变其流动行为的颗粒或聚合物添加剂。尽管已有大量实验和理论研究来理解牛顿流体的撞击动力学,但作为一个学术共同体,我们在理解当撞击流体具有非牛顿流变特性时这些动力学如何改变方面仍有很大进展空间。在这篇综述中,我们概述了复杂流体在固体表面撞击动力学研究的最新实验、理论和计算进展。在此,我们为多学科受众提供了该领域的概述。我们的讨论按两种主要材料构成进行划分:聚合物流体和颗粒悬浮液。在整个综述中,我们强调了有前景的未来方向,以及该领域正在进行的实验和理论挑战。

英文摘要:

The impact of fluid drops on solid substrates has widespread interest in many industrial coating and spraying applications, such as ink-jet printing and agricultural pesticide sprays. Many of the fluids used in these applications are non-Newtonian, that is they contain particulate or polymeric additives that strongly modify their flow behaviour. While a large body of experimental and theoretical work has been done to understand the impact dynamics of Newtonian fluids, we as a community have much progress to make to understand how these dynamics are modified when the impact fluid has non-Newtonian rheology. In this review, we outline recent experimental, theoretical, and computational advances in the study of impact dynamics of complex fluids on solid surfaces. Here, we provide an overview of this field that is geared towards a multidisciplinary audience. Our discussion is segmented by two principal material constitutions: polymeric fluids and particulate suspensions. Throughout, we highlight promising future directions, as well as ongoing experimental and theoretical challenges in the field.
