A device that can be used to attenuate noise generated in an engine nacelle of an aircraft is an acoustic liner. A conventional single degree of freedom (SDOF) acoustic liner is comprised of a perforated face sheet, honeycomb cells, and...
Active flow control can achieve substantial performance gains and meet the challenges of next-generation air vehicles and energy harvesting devices. The use of active flow control techniques with the deflecting flap or morphing surfaces...
Underwater vehicles suffer from reduced maneuverability with conventional lifting appendages due to the low velocity of operation. Circulation control offers a method to increase maneuverability independent of vehicle speed. However, ...
An accurate representation of air-sea interaction is crucial to the accurate numerical prediction of ocean, weather, and climate. It is known that sea surface temperature (SST) gradients and surface currents in the oceanic mesoscale...
Gravity measurements from the Gravity Recovery and Climate Experiment (GRACE) satellite measuring system show that Greenland is losing mass as water is lost to the ocean. Past work has suggested that the freshwater flux from Greenland, ...
How much warmer is the ocean surface than the atmosphere directly above it? Part 1 of the present study offers a means to quantify this temperature difference using a nonlinear one-dimensional global energy balance coupled ocean...
This study aims to examine the use of a fundamental thermal input for separation control and provide a design guideline via resolvent analysis. The use of the thermal actuator is motivated by the interest in the use of thermal-energy...
Fundamental to an understanding of El Niño/Southern Oscillation climate fluctuations is an understanding of the interannual equatorial Pacific surface flows, which advect the surface waters and change the sea surface temperature. While...
The polar regions of the world constitute an important sector in the global energy balance. Among other effects responsible for the change in the sea-ice cover like ocean circulation and ice-albedo feedback, the cloud-radiation feedback...
The northern part of the West Florida Shelf (WFS) bends sharply to form Florida's Big Bend coast. Eulerian acoustic Doppler current profiler measurements on this narrowing shelf, the first multiyear in situ measurements in this region, ...
The impinging jet flowfield observed during take-off and landing of a STOVL aircraft is known to be associated with several adverse effects such as strong acoustic emission, unsteady structural loads, loss of engine efficiency due to hot...
Cavity structures, like weapons bays and landing gear wells on aircraft, suffer from severe oscillations under high speed flow conditions. These oscillations are associated with intense surface pressure/velocity fluctuations inside the...
This dissertation seeks to understand physical processes in submerged and dry caves in Florida. First, for submerged caves, we prove the possibility of an upward saline water intrusion due to the Venturi effect occurring in a submerged...
