Web9 de out. de 2024 · Figure 2 shows the cavity patterns for the two tandem spheres entering into water with three different time intervals, i.e., Δ t = 1.5 ms, 3.3 ms and 6.6 ms, which are also compared with that of a single sphere. For all the three cases, the initial impact velocity of Sphere I is about 30 ± 0.5 m/s, close to that of Sphere II. WebAt the turn of the millennium a resurgence of interest occurred in water entry studies. During this time, two foundational papers on cavity formation and cavity dynamics were published, which describe the regimes into which all other water entry studies fall. The rst was written by Duez et al. (2007) who investigated when impacting spheres form air

The state of the jet cavity determines the aerator efficiency under different flow conditions. In the case of a low Froude number and low velocity, backwater is generated in the jet cavity. In severe cases, this backwater blocks the air intake holes … baztan bidasoa turismo elkargoa
