| Abstract: | Some fluid dynamic noise control approaches for gear pump, piston pump, control valve and duct are proposed by analyzing the causes of fluid dynamic noise and the basic mechanism of exhaust noise in torpedo thermal power system. It is shown that press and flux pulsation controls are the main measures for fluid dynamic noise control. By analyzing the exhaust noise frequency spectrum and the exhaust noise control methods, the muffler is considered a effective way of controlling exhaust noise. |
