Abstract : The report covers a feasibility study of the possibility of using the cavitation performance of standard bodies to measure the strength of water. An analytical cavitation model which utilizes a series of mathematically derived axisymmetric test bodies is combined with an acoustical cavitation occurrence counting instrumentation technique to establish an index which indicates the cavitation susceptibility of the test water in water tunnels. An equivalent size distribution of entrained microbubbles is proposed to represent the actual stream nuclei and to serve as the cavitation susceptibility index.
