Abstract. The hydrocyclone of main diameter 28mm with a typical variable diameter pipe structure was selected as the research object, and the interaction of the fluid and the structure was considered on the basis of the hypothesis of small deformation. The two-way fluid structure interaction (FSI) model of the hydrocyclone with variable diameter pipes was presented in this paper, and the related numerical simulation and experimental research was also carried out. The structure vibration characteristics of the structure were analyzed base on the fluid structure interaction, and the vibration characteristics of the structure were obtained. The vibration characteristics of the between the results of numerical simulation and experimental were consistent. Through above analysis showed that the two-way FSI calculation model of hydrocyclone with variable diameter pipe was reasonable. The influence of coupling effect on flow field couldn’t be ignored. The interaction between fluid and structure changed the movement characteristics of the structure, which should be considered in the design and application of hydrocyclone.

Keywords: fluid structure interaction, hydrocyclone, modal analysis, vibration characteristics.
