A supercavity can be formed at low speeds by ventilating non-condensable gas into the low-pressure region around a cavitating object (i.e., cavitator), termed as artificial or ventilated supercavitation (Kawakami and Arndt 2011). Ventilated supercavitation is generally characterized fishing vessel destination foundWebnumber of previous studies on the gas loss from ventilated supercavities (Epshtein 1973, Logvinovich 1973, Spurk 2002), fundamental understanding of supercavity closures is still lacking as demonstrated by a significant lack of concurrence on the empirical formulations and physical phenomena derived from cancer that starts with a p
