Cavity dynamics of water entry for spheres and ballistic projectiles
… coupled with improvements to an existing cavitation model lead to an improved bullet design that forms a narrower cavity and achieves higher speeds. Industrial applications include ship slamming, extreme waves and weather on oil platforms, sprayed adhesives, paint aerosols and ink jet …

Data Analysis of an Unsteady Cavitating Flow on a Venturi-type Profile
… (DMD), and Clustered-based Reduced Order Modeling (CROM), are applied to the snapshots of the fluctuating component of velocity to investigate instability modes of the cavitating flow. DMD and POD analysis yield multiple modes are corresponding to slow-varying drift flow, cloud-shedding, …

A Study of Instability Mechanisms Driving Cloud Cavitation: Experimental Analysis Using New Advanced Velocimetry and Evaluation of Numerical Models
Hydrodynamic cloud cavitation, characterized by the periodic shedding and violent collapse of large vapor structures, poses significant risks to the integrity and performance of hydraulic machinery. Despite extensive research, the precise interaction between competing shedding mechanisms, …

Oil-whirl instability in an automotive turbocharger
… system. To avoid over-complicated mathematical modeling, the influence of two such parameters: gyroscopic moment and shaft flexibility are first investigated in this thesis using linear stability theory to determine their significance. Effects of gyroscopic action are investigated using …
