This investigation studies the basic liquid jet-gas cavity interaction, accounting for compressibility, frequency and amplitude of jet oscillation, and fall characteristics of the undisturbed jet flow. The analysis reveals several new aspects of the liquid jet-gas cavity interaction: The phase angle between the jet origin and the cavity pressure fluctuation is a strong function of cavity compressibility and oscillation frequency; the amplitude of the cavity pressure fluctuation has resonance states which are related to phase angle and compressibility effects; the phase angle dependence on frequency of oscillation has well-defined upper and lower limits due to cavity compressibility limits.
