| Summary, etc | This paper describes results from the development of a water injection noise control system applied<br/>to an exhaust duct. A mist of water is introduced into an exhaust duct by injectors into the gas <br/>ow<br/>and is used to reduce the sound pressure level in the exhaust by several mechanisms, particularly<br/>through the absorption of energy required for the evaporation of the water vapour. This noise<br/>control method is investigated rstly with the aid of CFD software and then tested experimentally.<br/>The results from the CFD showed that there are signicant reductions in temperature, pressure<br/>and hence energy of the <br/>ow. The experimental prototype injection system showed inconclusive<br/>results due to systematic error. The instrumentation noise <br/>oor in every test was approximately<br/>100dB when the water injectors were activated. It is expected that the increase in the noise <br/>oor<br/>is created by the injected water causing vibrations in the pipe walls which is picked up by the<br/>microphone. It is proposed that a water injection based noise attenuation device could be eective<br/>with dierent implementation based on research theoretical results. |
