Abstract

The primary objective of this review is to consolidate our current understanding of the factors controlling the foamability of surfactant solutions under hydrodynamic conditions realized in various laboratory tests. In particular, two regimes of foam generation are considered: at low surfactant concentrations where the coalescence between the bubbles plays a crucial role, and a high surfactant concentration range where the hydrodynamic conditions are much more important for the final outcome of foaming. The review discusses the role of surfactant concentration, dynamic surface coverage, and surface forces acting between film surfaces for the foam generated in the surfactant-poor regime. Additionally, the interplay between the hydrodynamic conditions and the viscosity of the formed foams in the surfactant-rich regime is also discussed.

气泡大小和发泡性:表面活性剂和流体动力学条件的作用
本综述的主要目的是巩固我们目前对控制表面活性剂溶液在各种实验室测试中实现的流体力学条件下发泡性的因素的理解。其中特别考虑了泡沫产生的两种情况:在表面活性剂浓度较低的情况下,气泡之间的凝聚起着关键作用;而在表面活性剂浓度较高的情况下,流体力学条件对最终的发泡结果更为重要。综述讨论了表面活性剂浓度、动态表面覆盖率和薄膜表面之间的表面力对贫表面活性剂条件下产生的泡沫所起的作用。此外,还讨论了在表面活性剂丰富的条件下,流体动力学条件与所形成泡沫的粘度之间的相互作用。

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
