Hydroacoustic characterisation of the AMC cavitation tunnel

This paper presents recent results from an Industry-University-Defence collaborative project whose aim is to characterise the hydroacoustic environment of the Australian Maritime College Cavitation Tunnel. After summarising the operation of the tunnel, a methodology for measuring and processing the hydroacoustic measurements is presented that includes a technique for reducing the level of turbulent wall pressure fluctuations on the hydrophone measurement. The background noise levels of the tunnel are presented for a variety of operating conditions and they compare favourably with other hydroacoustic test faciltities internationally.Con Doolan, Paul Brandner, Daniel Butler, Bryce Pearce, Danielle Moreau and Laura Brookshttp://www.acoustics.asn.au/conference_proceedings/AAS2013/http://www.acoustics.asn.au/conference_proceedings/AAS2013/papers/AAS2013-Information.pd
