Abstract
Self-propelled particles are commonly found in a large number of planktonic organisms such as bacteria,fungi,and algae in nature,and researchers have taken a long interest in exploring their swimming mechanisms for more than a century.Especially in the past 20 years,with the development of computational fluid dynamics and flow display technology,as well as the need for the design of synthetic self-propelled particles and micro-swimming devices,self-propelled particles have become the forefront and hotspot of current research in the field of fluid mechanics.This paper first introduces the swimming characteristics of common self-propelled particles,leading to a classic"squirmer"type self-propelled particle model.On this basis,a systematic introduction and summary of the theoretical and numerical simulation research of"squirmer"will be conducted.Finally,the main challenges and opportunities faced by the current research will be summarized.
