Cavitation inception studies made on models in a recirculating water tunnel fail to correlate with similar studies on prototype bodies. This report considers the effect which free-gas nuclei in the water may contribute to this problem. Cavitation model tests were conducted using new instrumentation to measure the amount and size of the gas nuclei present in the flow.
The inception of cavitation and the acoustic noise resulting from cavitation were both determined to be profoundly influenced by the character of the gas nuclei present in the liquid.
