Vorticity control for efficient propulsion
Vorticity control is a new paradigm in propulsion hydrodynamics. In this thesis, we study fish-like propulsion strategies as concepts in vorticity control. Our motivation for this research stems from the remarkable capabilities of fish to propel and maneuver in ways presumably optimized by …

Vorticity transfer through rapid area change
… generation of maneuvering forces by using rapid vorticity transfer into the fluid through a rapid motion as observed in some animals. In this study a NACA 0012 foil was towed steadily at Reynolds number of 14000, then the foil is rapidly accelerated in the transverse direction. Two different …

Vorticity shedding over two-dimensional bodies
The vorticity shedding characteristics in attached and separated regions were investigated over three configurations, namely a backward facing circular arc, an ellipse at an angle of attack and a pitching airfoil. A fully automated data acquisition system was developed, including a two-component …

Global vorticity shedding for a vanishing foil
… several aspects of the phenomenon we call global vorticity shedding. Global vorticity shedding occurs when an object in viscous fluid suddenly vanishes, shedding the entire boundary layer vorticity into the wake at once. In our experiments we approximate the disappearance of a towed foil by …

Observations of surfzone vorticity using optical remote sensing
… and theory. Here, novel observations of surfzone vorticity at small [O(10m)] and large [O(100m)] spatial scales are presented and related to incident wave conditions and the measured underlying bathymetry. Field experiments were conducted at a sandy beach on the Atlantic Ocean, and nearshore flows …

Vorticity Modeling for the Flow Over Surface-Mounted Prisms
Vorticity modeling is used to simulate the flow around a surface-mounted prism. The objective is to examine whether vorticity modeling can give satisfactory information about surface pressure fluctuations which are mostly due to the outer or inviscid flow. Differences between results obtained with …

Unsteady pressure and vorticity fields in blade-vortex interactions
… algorithms were written to obtain vorticity and pressure in the data field. Computer animation of the unsteady vorticity was accomplished first with a Fortran code written for an Apple Macintosh computer and later with a commercial software package for a SUN Microsystems graphics …
