In the present study, interactions between a single particle and a single Burgers vortex are observed by using 2DPIV measurements as elementary interactions for modeling particle-laden turbulent flows. We focus on the interaction between a Burgers vortex and wake structure generated by a settling particle. It is found that the interaction between the vortices shed from the particle and the Burgers vortex induces the large fluctuation in the circulation of the vortex. Moreover, fragmentation and mergence of the Burgers vortex core are observed.
