Cavity dynamics of water entry for spheres and ballistic projectiles
… solutions describing criterion such as cavity formation, depth of deep seal, and trajectory for all impact parameters studied. The topic is extended to the impact of high-speed projectiles or bullets. Through experimentation the trajectory, cavity size, and forces acting on the …

Stochastic dynamics and fluctuation theorems in Brownian, feedback-controlled, and optical cavity systems
This thesis investigates stochastic dynamics in a range of classical systems, with a focus on fluctuation theorems and the physical interpretation of the quantities entering these relations. It begins with an investigation of the added mass effect in harmonically coupled underdamped Brownian …

On falling spheres : the dynamics of water entry and descent along a flexible beam
… to characterizing the shape of the resulting air cavity in the limit where cavity collapse is strongly influenced by surface tension. A parameter study reveals the dependence of the cavity structure on the governing dimensionless groups. A theoretical description is developed to describe the …

Hydrodynamic cavitation for effluent treatment: using vortex-based cavitation devices
… model by coupling computational fluid dynamics (CFD) and cavity dynamics models to the per-pass modelling methodology, which was used to simulate the performance of vortex-based hydrodynamic cavitation devices and in general any hydrodynamic cavitation device. The multi-layer modelling …

Computations of fully nonlinear three-dimensional wave-body interactions
Nonlinear effects in hydrodynamics of wave-body interaction problems become critically important when large-amplitude body motions and/or extreme surface waves are involved. Accurate prediction and understanding of these fully nonlinear effects are still challenges in the design of surface ships …
