摘 要:The hydrodynamic performance of a three-dimensional finite-length rotating cylinder is studied by means of a physical tank and numerical ***,according to the identified influencing factors,a hydrodynamic performance test of the rotating cylinder was carried out in a circulating water *** order to explore the changing law of hydrodynamic performance with these factors,a particle image velocimetry device was used to monitor the flow ***,a computational field dynamics numerical simulation method was used to simulate the flow field,followed by an analysis of the effects of speed ratio,Reynolds number,and aspect ratio on the flow *** results show that the lift coefficient and drag coefficient of the cylinder increase first and then decrease with the increase of the rotational speed *** trend of numerical simulation and experimental results is similar.
