Abstract

Flow-generated noise problem is a common noise problem encountered in ventilation systems. Being able to accurately predict this type of noise at the design stage is of engineering importance. Recent experimental and theoretical studies conducted by Mak et al have suggested that it is possible to predict the flow-generated noise produced by multiple in-duct strip spoilers. The conventional measurement approach requires the use of an expensive special combined acoustic and aerodynamic experimental facility. An alternative to the use of specialised acoustic and aerodynamic facility which is currently gaining favour in building engineering is the use of Computational Fluid Dynamics (CFD) software packages. CFD is a very powerful design tool that is able to predict the behaviour of fluid flow regimes. It has been applied to a number of areas of building engineering such as smoke extraction and ventilation with considerable success. This paper will discuss the possibility of further developing the prediction method for flow-generated noise using CFD technique.
