On the gas loss from ventilated supercavities
Web1 de out. de 2016 · Here γ is the specific heat ratio of the gas inside the cavity, K is a constant for a given cavity, S is the mean cavity surface area, R o is the tunnel radius, and r o is the mean cavity radius. Previously, Eq. (1) was used to successfully predict the resonance/pulsation frequencies of ventilated supercavities (Skidmore et al., 2015a).
