Abstract
When underwater vehicles crosse the medium and enter water at high speed,an entry cavity is usually formed.The hydrodynamic force generated by the coupling interaction between the entry cavity and the vehicle has an important influence on vehicle motion after water entry.The force resulting from the reciprocating flapping motion of the vehicle tail inside the cavity is one of the key factors affecting the underwater motion of the vehicle.In this paper,under the condition of minimizing the coupling interaction between the motion and the cavity,numerical simulations with different tail flapping frequencies and swinging amplitudes of the vehicle are carried out to obtain the variation law of the cavity and the tail hydrodynamic characteristics under the specified motion law.This can provide a reference for deeper understanding of the hydrodynamic changes during the tail-slap process.The results indicate that within the scope of this study,when the tail-slap frequency is low(f=5 Hz),the tail-slap normal force is more significantly influenced by the vehicle's angle of attack(tail submersion angle).When the tail-slap frequency is high(f=100 Hz),the tail-slap normal force is more significantly influenced by the angular velocity of the vehicle.Under the specified motion law,the peak of the tail flapping normal hydrodynamic force is linearly related to the flapping amplitude.关键词
