Added Mass and Vortical Impulse: Theory and Experiment
… force regardless of the presence of a vortical wake. This generalized added-mass and circulatory (GAMC) force decomposition is derived from impulse theory using a Helmholtz decomposition of the velocity field, and is valid for rigid bodies of any shape in unbounded incompressible fluid …

Numerical Modeling of Synthetic Vortical Disturbance Interactions Using OpenFOAM
<p>Nowadays, the number of Advance Air Mobility (AAM) Electic Vertical Take-off and Landing (eVTOL) concepts is rapidly increasing due to their capability of vertical take-off and landing at vertiports located on rooftops of tall urban buildings, which does not require using the ground space in a …

Three-dimensional vortical structures in the wake of a flexible flapping foil
… gain a qualitative view of the three-dimensional vortical structures of a flexible flapping foil at Reynolds number 164. Flexible foils were fabricated, coated with fluorescent dye, and towed with heave and pitch in a large glass tank. The foil cross section is a NACA 0030 foil shape, and the foil …

Kinematic and vortical wake patterns of rapidly maneuvering fish and flapping foils
This project examines the choreography of high speed turns performed by Danio aequipinnatus, giant danio, with the goal of understanding the motions that allow this species to perform its highly efficient maneuvering. Observations of the turns were made using high-speed video to determine general …

Analysis of the vortical flow around a 60 degree delta wing with vortex flap
Subsonic wind tunnel investigations were conducted on a 60° swept, flat plate, delta wing with a leading edge vortex flap. The pressure distributions were measured over a range of angles of attack starting from zero to 40° in 5° interval and flap deflection angles from zero to 45° with 5° …

Near Wall Behavior of Vortical Flow around the Tip of an Axial Pump Rotor Blade
This dissertation presents the results from an experimental study of three-dimensional turbulent tip gap flow in a linear cascade wind tunnel with 3.3% chord tip clearance with and without moving endwall simulation. Experimental measurements have been completed in Virginia Tech low speed linear …

Implications of Vorticity and Disorder on Quantum Transport in Topological Semimetals
… systems. In the first part, we investigate vortical and converse vortical effects in Weyl semimetals that break inversion symmetry. Using semiclassical and quantum kinetic frameworks, we analyze how Berry curvature and orbital magnetic moments generate charge and current responses in the …

Numerical investigations of vortex dynamics: bursting, twist waves, and sensitivity analysis
Vortical structures are ubiquitous in real-world fluid flows, from the vortices generated by swimming fish to the wakes of aircraft and propellers. They form the backbone of high Reynolds number turbulent flows. Their dynamics are governed by non-linear processes, leading to a range of vortical …

The Near Wake of a European Starling
… imply the presence of (secondary) streamwise vortical structures, in addition to the wing tip vortices. The lack of downwash during the upstroke and the suggestion of secondary streamwise vortical structures constitute a deviation from a wake model which has been developed and supported by …
