| Abstract: | A novel device for attenuating the effects of fluid flow pulsations was presented.The advantages of the device are smaller size,easy installation and good attenuation effects,so it has obvious advantages compared with the expansion chamber silencer.The result of the experiment shows that the tightly packed structure has a satisfactory acoustic attenuation performance in a wide frequency range.The developed silencer is applicable for the large diameter pipeline to attenuate the noise of pump and valves. |
