On the three-dimensionality and spanwise variations of cloud cavitation: A combined numerical and experimental study
Cloud cavitation that forms around a two-dimensional hydrofoil may exhibit three-dimensional characteristics. This study investigates the spanwise variations of cloud-cavitating flows through comprehensive analyses of both numerical results and experimental snapshots. Experiments were conducted in the cavitation tunnel, utilizing high-speed cameras to record the evolution of cavitation, while the cavitating flow of the same configuration was simulated using detached eddy simulation (DES). The three-dimensional shedding phenomena of cloud cavitation, characterized by spanwise variations, are observed in both numerical and experimental results, impacting on the oscillation of hydrodynamic forces. According to the investigation on the spatial-temporal evolution of flow field, two distinct patterns in terms of spanwise shedding of cloud cavitation, namely complete and incomplete shedding, are identified.
