Simulation Analysis of the Effects of the Flow around Underwater Moving Bodies on the Acoustic Signal
2021 OES China Ocean Acoustics (COA)(2021)
摘要
The underwater moving bodies interacting with the water flow form a complex flow field. The changing flow field can cause the time-varying Doppler frequency shift of the acoustic signal propagating in the flow field. In this paper, the finite volume method is used to simulate the flow field behind the underwater cylindrical moving body and the horizontal rudder with different deflection angles. Th...
