TL;DR: In this article, the authors investigate ventilated cavitating flow structures with special emphasis on vortex shedding dynamics via combining experimental and numerical methods, and the results show that the flow patterns can be classified into two principally different categories: structures mainly with vortex shedding (namely Benard-Karman vortex street; Benard Karman vortex Street with vortex filaments and Aligned vortices) and relatively stable structures (such as Aligned Vortices with Re-entrant jet; Re-enterrant jet and Stable supercavity).

TL;DR: In this paper, the authors investigated the unsteady pressure fluctuation characteristics in the process of breakup and shedding of unstrainedy sheet/cloud cavitating flows via combined experimental and computational methods.

TL;DR: In this paper, the authors investigated the ventilated cavitating flow structure by combining experimental and numerical methods, and the results showed that when the gas entrainment coefficient Qv is constant, two typical mechanisms of the gas leakage exist at different Fround numbers Fr, namely toroidal vortices mode and two hollow tube vortice mode.

TL;DR: In this article, the authors investigated the cavitation evolution and excited pressure fluctuation in unsteady sheet/cloud cavitating flows in a convergent-divergent channel using a combination of experimental and computational studies.

TL;DR: In this article, a flow pattern map is constructed to depict the flow pattern and structures, i.e. the range of Fr and C Q. As shown in the flow patterns map, four relatively stable states of a ventilated cavity could be observed, which include three partial cavities, namely, continuous transparent and asymmetric cavity (CTAC), bubbly cavity (BC), and super cavity (SC).
