A numerical study of flow-structure interactions with application to flow past a pair of cylinders
… on spectral/hp elements is employed. Structural motion implies changes on the boundaries of the flow domain. An Arbitrary Lagrangian Eulerian (ALE) scheme is incorporated to efficiently move the mesh without remeshing. Efficient three-dimensional simulations with periodicity in at least one space …

Improved Underwater Vehicle Control and Maneuvering Analysis with Computational Fluid Dynamics Simulations
… with coefficients determined from the results of prescribed motion CFD simulations. CFD analyses focused on supporting the design of a general purpose AUV are also presented.

Aspects of dynamically enhanced electromagnetic fields from charged relativistic sources in a beam pipe
… …fields produced by charged sources in prescribed motion, moving in an infinitely long cylindrical beam pipe with perfect electrically conducting boundary conditions, is investigated in order to understand dynamic …field effects. In the ultra-relativistic limit analytic field solutions …

Slamming of High Speed Craft: A Parametric Study of Severe Cases
… of high-speed surface vessels. The controlled motion experiments presented in this thesis were designed to be an intermediate step between vertical water entry tests of a wedge and a traditional tow tank experiment of a planning hullform in waves. This allowed a deeper study of the hydrodynamic …

Effect of Kinematics and Caudal Fin Properties on Performance of a Freely-Swimming Fin
… vehicles have been using propellers for locomotion but they are not only inefficient but generate large acoustic signature. Researchers have taken inspiration from efficient swimmers like fish to address the issue with alternate propulsion mechanism. Mostly, research on fish locomotion …

An Experimental Investigation into the Passive Reconfiguration of Flexible Plates Near a Free Surface
… the physics surrounding a flexible plate under prescribed oscillatory heaving motions. White light movies were recorded at constant frequency and varying proximity to the free surface to investigate the change in reconfiguration as the plate approaches the free surface. Results, analyzed in …

Numerical simulation of the flow in model skeletal muscle ventricles
… with a truncated apex using sinusoidally prescribed motion of the wall. With this model, two vortex rings could be predicted as in the experiments. The spherical-end model also gave good agreement with experimental flow patterns (ludicello et al., 1994). Frequency-dependent studies were …
