“…For the aft part of the cavity sheet, where the distinction between liquid and vapor is not so clear, some wake model must be introduced. Examples are, amongst others: Furness & Hutton [76], Chen & Heister [37], Deshpande et al [59], Hirschi et al [92], Sussman et al [187], Van der Pijl [205] and Dijkhuizen [61]. These methods do not allow the description of the unsteady behavior of pulsating cavities, including phenomena like the re-entrant jet, cavity breakdown or vapor cloud shedding.…”
