Bioinspired movement of gas bubbles: composition, applications, generation, contact angle, and movement – an overview

Abstract

Gas bubbles are of interest in various applications including biomedicine, food production, drag reduction, water treatment, oil removal and surface cleaning. Therefore, studying gas bubbles in its entirety and their movement is important. In this paper, an overview is presented on gas bubbles in terms of their composition, applications, generation, and contact angles, with focus on their movement on bioinspired conical surfaces and triangular patterns. Effects of parameters including gas bubble volume, orientation, tip angle, surface wettability, and liquid were also presented.
