Effects Of Transport Properties And Flame Unsteadiness On Nitrogen Oxides Emissions From Laminar Hydrogen Jet Diffusion Flames
… the coupled effects of transport properties and unsteady fluid dynamics have been conducted on laminar, acoustically forced, hydrogen jet diffusion flames diluted by argon and helium. The primary purpose of this research is to determine how the fuel Lewis number and the flow unsteadiness play a …

Perching with fixed wings
… where the rotor or propeller forces dominate the dynamics of the aircraft [3, 4, 5]. However, as our flying machines scale down to smaller sizes (e.g. Micro Aerial Vehicles) operating at low Reynold's numbers, viscous forces dominate propeller thrust [6, 7, 8], causing classical control (and …

Vehicle Control in Full Unsteady Flow Using Surface Measurements
… control of a vehicle maneuvering in a full unsteady flow field. The approach to the solution is focused in three main areas: modeling of a vehicle in full unsteady flow, control of a vehicle in full unsteady flow, and synthesizing the fluid loads for use in control of a vehicle maneuvering …

Effect of frontal gusts and stroke deviation in forward flapping flight and deconstructing the aerodynamics of a fruit bat
… and dynamic wing conformation have on the fluid dynamics of flapping flight. The primary motivation is to better grasp the fundamental fluid phenomena driving efficient flapping flight in the Reynolds number regime of birds, bats, and man made fliers of similar scale. The CFD solver …

Experimental Investigations into the Fluid Dynamics and Forcing Underlying Cross-flow Turbine Operation
… to converting the kinetic energy in a moving fluid to electricity. Recent cross-flow (i.e., vertical axis) turbine research has yielded substantial performance gains through the exploitation of unsteady fluid dynamics for individual turbines and mutually beneficial interactions between …

Three-Dimensional Unsteady Hydrodynamics of Tidal Turbines
… to the fluctuating loads that result from the unsteady flow, either from high-cycle fatigue or from extreme loading events exceeding the ultimate tensile strength of components. In this thesis, the problem of unsteady loading is addressed by identifying the shortcomings of the models currently …
