| Abstract: | In this paper, the frequency of vortex shade and the corresponding velocity distribution are studied for the flow around trashrack. The experiment is a part of the study on flow-induced vibration of trashracks of Tianhuangping pumped-storage station.A two-dimension Doppler Laser velocimet and frequency follower system was used in this expeximent. The models were made of different materials and in various scales.The results have been used in the design of Tianhuangping project, and can be used as a reference for studying the flow-induced vibration of other trashracks as well. |
