Analysis of Hydrodynamic and Fluid Noise Performance of Biomimetic Rim Thrusters
摘要
Abstract
Humpback whales exhibit agility that does not match their large size when capturing preys,which is due to the nodular protrusions on their pectoral fins.To improve the performance of the propulsion system and to reduce the underwater radiation noise caused by it,the fin like limbs of the humpback whale are applied to the design optimization of the wheel rim thruster using biomimetic principles,and the hydrodynamic and fluid noise performance of the biomimetic wheel rim thruster is analyzed using STAR-CCM+software.The results show that biomimetic nodules can improve the efficiency of wheel rim thrusters,and the higher the speed,the greater the increase in efficiency,with an increase of 3.16%at the highest efficiency point.In addition,biomimetic wheel rim thrusters can reduce near-field and far-field noise,with a maximum reduction of 20 dB for both near-field and far-field noise at 1 150 Hz,and an average reduction of 8 dB for far-field low-frequency noise.关键词
