Witryna12 kwi 2024 · An interpretation is that at the beginning of the event, the directional jetting and sustained finite extended source produces a directional acoustic wavefield. Then, as the jet flow decelerates (signal amplitude decreases), the extended/directional source effects correspondingly diminish and the infrasound source is mostly localized at the … Witryna15 maj 2024 · Impact jetting occurs during the earliest stage of impact cratering when the impactor is still making contact with the target (e.g., Birkhoff et al., 1948, Walsh et al., 1953). The jet contains the first material ejected, is highly shocked, and is ejected at speed exceeding the impact velocity. The total mass of jetted ejecta is small ... Witryna13 kwi 2024 · The jet impact from a collapsing bubble is an important mechanism of structural damage in underwater explosions and cavitation erosion. The Boundary Integral Method (BIM) is widely used to simulate nonspherical bubble dynamic behaviors due to its high accuracy and efficiency.
