Hydraulic acoustic and fluid dynamic optimization of submarine bow shapes.
We developed an iterative design process to reduce fluid dynamic noise levels using the general-purpose tool STAR-CCM+.
The sources of self-noise generated during the operation of watercraft can be classified into three categories. Propeller noise is generated by cavitation that occurs as the rotational speed increases, resulting in noise from the screw. Hydrodynamic noise includes all noise sources arising from the movement of submarines underwater. Mechanical noise is the mechanical sound produced by engines, control equipment, auxiliary machinery, etc., installed on the submarine. *For more detailed information, please refer to the related links.
