Suppression of the Hydrodynamic Noise Induced by the Horseshoe Vortex through Mechanical Vortex Generators

Applied Sciences, 2019
The hydrodynamic noise from the horseshoe vortex can greatly destroy the acoustic stealth of underwater vehicles at low frequency. We investigated the flow-induced noise suppression mechanism by mechanical vortex generators (VGs) on a SUBOFF model. Based

Hydrodynamic Numerical Analysis of Wave Pattern Due to the Motion of Suboff 5470 Underwater Vehicle Near the Free Surface

نشریه مهندسی دریا, 2019
The wave pattern generated by motion of autonomous underwater vehicle (AUV) near the water free surface is one of the significant factors in order to identify the AUV. In this research, firstly simulating the flow with constant velocity around the Wigley
