摘　　要：Particles(including solid particles,liquid drops and gas bubbles)are ubiquitous in a large number of natural processes as well as in industrial productions.Their behaviors are of fundamental importance in multiphase systems since the existence of such dispersed particles influences the momentum,mass and heat transport behaviors in these systems.Up to now,a vast body of literature has been published in dealing with the transport phenomena related to a particle surrounded by a fluid under various physical circumstances.In this paper,principal research results for the transport process of a single spherical particle in pure extensional and simple shear flows presented in the literature,including our recent work,are generally reviewed in order to give a comprehensive knowledge in this area.Particles （including solid particles, liq- uid drops and gas bubbles） are ubiquitous in a large number of natural processes as well as in in- dustrial productions. Their behaviors are of funda- mental importance in multiphase systems since the existence of such dispersed particles influences the momentum, mass and heat transport behaviors in these systems. Up to now, a vast body of litera- ture has been published in dealing with the trans- port phenomena related to a particle surrounded by a fluid under various physical circumstances. In this paper, principal research results for the trans- port process of a single spherical particle in pure extensional and simple shear flows presented in the literature, including our recent work, are generally reviewed in order to give a comprehensive knowl- edge in this area.
