Abstract: | It is well known that the acoustic performance of silencing elements decreases with an increase in exhaust gas flow. Tests were conducted on three orifice geometries of side-branches on an adaptive quarter-wave tube to determine which was the least compromised by the high-speed exhaust gas passing over the side-branch. The geometries that were tested included a sharp edge, a backward inclined branch, and a bell mouth. The experimental results show that the side-branch with a bell-mouth resulted in the greatest noise reduction by an adaptive quarter-wave tube. |
