Design of PIV Experiment Platform for Rotating Cylinder Based on Magnus Effect

In order to visually show the changes in the tail flow field of the rotating cylinder based on the Magnus effect, let students visually understand and study the Magnus effect and the evolution process of the tail flow field vortex of the rotating cylinder from the generation to the disappearance, a particle image velocimeter (PIV) experiment teaching platform for rotating cylinder based on the Magnus effect is designed. The platform adopts advanced PIV technology and is mounted on a circulating tank test system. It can be used to study the influence of the inflow speed, cylinder rotation speed, cylinder type on the change of the tail flow field of different cross-sections of the cylinder, and analyze the hydrodynamic performance of a rotating cylinder through the changes in the tail flow field. The purpose of this experimental platform is to stimulate students’ interest in learning through vivid and specific images of the flow field, cultivate their hands-on ability, improve their innovation ability, and lay a good foundation for future scientific research and exploration.
