Research on Simulation and Acoustic Signal Characteristics of Underwater Vehicle Wake Vortex Fields
摘要
Abstract
To investigate the application of underwater vehicle wake vortices in underwater target detection,simulation and analysis of wake vortex fields under straight navigation,pitch,and yaw conditions are conducted using Fluent software and the fully appended Suboff model.The influence of the wake vortex fields of underwater vehicles on the phase characteristics of acoustic signals are studied.The results demonstrate that there is obvious phase transition in acoustic signals when vertical linear array is used to monitor yaw-induced wake vortices,while similar phase discontinuities occur when horizontal linear array is used to observe pitch-generated vortices.In contrast,straight navigation produces symmetric wake fields that prevent detectable phase transition in either array configuration.Variations in vehicle motion parameters alter spatial distribution and intensity of wake vortices,thereby affecting phase jump characteristics.By leveraging the correlation between vehicle motion states and wake vortex fields,along with the association between wake vortex fields and acoustic signal phase jumps,an indirect detection method could be developed for underwater vehicle detection and motion state identification.关键词
