WebWe describe jet drop production, from ensembles of high fidelity numerical simulations of bubble bursting, validated against experimental results. The number of jet drops, their size, and velocity are controlled by the ratio of the bubble size, R b , and the visco-capillary length, , where γ is the surface tension, ρ w , μ w the water ... WebWith an increased drop size, the range of the sound pressure amplitude and energy of the bubble noise becomes wider. As shown in Figure 14b, the sound energy of bubbles produced by 2.5 and 3.9 mm drops decreases with the resonance frequency.
