Determining the vibration frequencies of a pump for a high-density fluid

Michiel Van Damme, Kirill Makhov

Research output


This work focuses on FSI simulations of an axial pump in lead-bismuth eutectic (LBE). Due to the high density of this liquid, the dynamic behavior of the pump blade is affected by an added mass and added damping effect, which needs to be
investigated. A blade of the impeller of the pump is first analyzed in vacuum using a computational structural mechanics solver. Then, the flow around the blade is resolved using a computational fluid dynamics solver and eventually, both solvers
are combined in a fluid-structure interaction simulation using the open-source code CoCoNuT of Ghent University. The resulting simulation of a blade vibrating in LBE is analyzed in order to extract the modal characteristics. As this is early
work in simulating an impeller in a high density fluid, the main focus of this lies in determining a methodology which can be used in further research.
