Descripción del proyecto As outlined in the Strategy Paper ‘Research for a Quieter Europe in 2020’, written by the CALM network and funded by the European Commission Research Directorate-General, significant research investments are needed to further reduce the road traffic noise in Europe. A major contributor to the noise, especially in urban environments, is the vehicle exhaust system. Noise attenuation of vehicle combustion engines is achieved by incorporating efficient mufflers in the exhaust systems. However, these mufflers might become flow-excited noise generators, aero-acoustic noise sources, themselves. At the host institute, a state-of-the-art hybrid method to study this noise generation has recently been developed. The radiation of the generated sound to the environment is mainly originating from the tailpipe end of the exhaust pipe. The tailpipe end jet flow has a pulsating nature and a temperature different from the ambient temperature. These aspects influence the noise radiation to the environment, yet to what extent is so far an open question. In EXPLICA, the state-of-the-art method developed at the host institute will be used to compute this exhaust pipe noise radiation. The research Fellow already is an expert in applied acoustics and has a high interest in the field of fluid dynamics. EXPLICA provides the opportunity for the researcher to combine both domains and to be hosted at an internationally renowned research group in the field of aeroacoustics. Apart from a well established scientific training environment, the researcher will also be able to participate in a professional organisation of complementary skills training. Combination of the unique scientific perspective, the international experience and the opportunity to set up an own network of aeroacoustic experts, will provide the researcher with very good career perspectives with respect to building up his own academic career.
