Article Preview

A study of the Herschel-Quincke (HQ) tube concept for the reduction of noise in circular ducts is presented here, which contain the models, the attenuation conditions and the acoustic characteristics of HQ tube without flow and with mean flow. Then the simulations have been done by using GT-POWER, which explain the influences on the acoustic characteristics of the angle between the main duct and the bypass duct and the changes of the diameters. The results show that the angle has an impact with flow, no effect without flow, and both of them are affected by the changes of the diameters.
