Offshore Wind Energy: Simulating Local Offshore Wind Turbine, Ian P. Aquino
Offshore Wind Energy: Simulating Local Offshore Wind Turbine, Ian P. Aquino
Mechanical & Aerospace Engineering Theses & Dissertations
Dominion Virginia Energy is looking at the possible creation of an offshore wind plant as a renewable source of electricity to be located off the coast of Virginia Beach. This thesis reports on a computer simulation based on local wind conditions and possible single wind turbine installation.
The National Buoy Data Center keeps records of the local wind conditions gathered in real time and available to the public. These data give a general overview of the wind conditions in Virginia Beach which is used to simulate atmospheric boundary layer (ABL) flow conditions and is subsequently used as input data for …

Performance Analysis Of A Rankine Cycle Integrated With The Goswami Combined Power And Cooling Cycle, Ricardo Vasquez Padilla, Antonio Ramos Archibold, Gokmen Demirkaya, Saeb Besarati, D Yogi Goswami, Muhammad M. Rahman, Elias L. Stefanakos
Dr Ricardo Vasquez Padilla
Improving the efficiency of thermodynamic cycles plays a fundamental role in reducing the cost of solar power plants. These plants work normally with Rankine cycles which present some disadvantages due to the thermodynamic behavior of steam at low pressures. These disadvantages can be reduced by introducing alternatives such as combined cycles which combine the best features of each cycle. In this paper, a combined Rankine–Goswami cycle (RGC) is proposed and a thermodynamic analysis is conducted. The Goswami cycle, used as a bottoming cycle, uses ammonia–water mixture as the working fluid and produces power and refrigeration while power is the primary …
Effect Of Pressure Drop And Reheating On Thermal And Exergetic Performance Of Supercritical Carbon Dioxide Brayton Cycles Integrated With A Solar Central Receiver, Ricardo Vasquez Padilla, Yen Chean Soo Too, Andrew Beath, Robbie Mcnaughton, Wes Stein
Effect Of Pressure Drop And Reheating On Thermal And Exergetic Performance Of Supercritical Carbon Dioxide Brayton Cycles Integrated With A Solar Central Receiver, Ricardo Vasquez Padilla, Yen Chean Soo Too, Andrew Beath, Robbie Mcnaughton, Wes Stein
Dr Ricardo Vasquez Padilla
Concentrated solar power using supercritical carbon dioxide (S-CO2) Brayton cycles offers advantages of similar or higher overall thermal efficiencies than conventional Rankine cycles using superheated or supercritical steam. The high efficiency and compactness of S-CO2, as compared with steam Rankine cycles operating at the same temperature, make this cycle attractive for solar central receiver applications. In this paper, S-CO2 Brayton cycle is integrated with a solar central receiver that provides heat input to the power cycle. Three configurations were analyzed: simple, recompression (RC), and recompression with main intercooling (MC). The effect of pressure drop in heat exchangers and solar receiver …

International Conference on Hydroinformatics
Renewable energy usually refers to those natural sources of energy which are possible to use without diminishing the resource and the current European target is to source 20% of its energy from renewable sources by 2020. The marine current turbine (MCT) is an exciting proposition for the extraction of renewable tidal and marine current power. It is gaining momentum as a viable technology and is currently the subject of much attention and research. However, the numerical predication of the power performance of a marine current turbine under a free surface is difficult due to its complex geometry, fluid-structural interactions and …
Bird Mortality In The Human Built Environment, Stacie Schwartz
Bird Mortality In The Human Built Environment, Stacie Schwartz
Honors Theses
Human development is having a detrimental effect on bird populations around the world. One hundred million to one billion birds are killed every year from colliding with human-built structures. I explored factors influencing the inability of birds to avoid man-made structures. If we can better understand these reasons, we can find solutions to this problem. After a known bird avoidance method, fritted glass, was installed in the Wold building, I investigated whether this glass actually deters birds from striking windows. Strikes on windows were noted daily through observation of specific windows on campus. Results show that vegetation outside of windows …
