Design Of Wind Turbine Tower Height And Blade Length: An Optimization Approach, Ryan Wass
Design Of Wind Turbine Tower Height And Blade Length: An Optimization Approach, Ryan Wass
Mechanical Engineering Undergraduate Honors Theses
The wind industry is a fast growing market and is quickly becoming competitive with traditional non-renewable energy resources. As with any developing industry, research must continually be redefined as more complex understandings of design variables are learned. Optimization studies are common ways to quickly refine design variable selections. Historical wind turbine data shows that the tower hub height to rotor diameter ratio scales almost linearly. However there is no specific rule that dictates the optimum hub height for a given diameter. This study addresses this question by using an Excel based optimization program to determine the height to diameter ratio …
The Correlation Between Energy Cost Share, Human, And Economic Development Using Time Series Data From Australasia, Europe, North America, And The Brics Nations, Ryan Roberts, Josephine Kaviti Musango, Alan Colin Brent, Matthew K. Heun

This paper investigates how a change in a region's energy cost share (ECS), a ratio of a region's energy expenditure as a fraction of its gross domestic product (GDP), affects the region's social and economic development. Nations from four regions of the world, namely Australasia, Europe, North America, and the BRICS nations (Brazil, Russia, India, China, and South Africa) were chosen for this study. Using time series data from the period of 1978 to 2010, the annual ECS of each country was compared to the year-on-year GDP change, as well as the components of the human development index (HDI). High …
Applications Of Latent Heat Storage Using Phase Change Materials, Daniel Giroux
Applications Of Latent Heat Storage Using Phase Change Materials, Daniel Giroux
Honors Theses
Thermal Storage Systems are gaining more attention in recent years with the increased emphasis on more renewable energy sources. Energy storage is necessary whenever there is greater amounts of energy being produced than is required. Various improvements to the conventional heat storage system can be made by integrating latent heat storage into the conventional heat storage system. Latent heat storage can be utilized for thermal storage applications by using phase change materials, materials that will undergo a change in their physical state in the temperature range desired for heat storage.
Analysis was conducted on four different waxes considering the waxes …

Principles Of Wind Energy Production, Willie Haynes, Dianne Lhotte, Johnetta Moore
Principles Of Wind Energy Production, Willie Haynes, Dianne Lhotte, Johnetta Moore
ENERGY Research and Lesson Plans
Three public school teachers designed basic wind turbine energy production tests to help them teach wind energy principles to middle and high school students. Variables affecting wind turbine energy production were identified (distance from wind tunnel, blade design, angle of attack, and wind speed), and experiments were conducted to test each variable. This research aligns with Georgia DOE curriculum standard STEM-FET-3.7: Apply STEM knowledge and skills through hands-on research and lab experiments that are focused upon recreating the inventions and social solutions that were realized in the past, present, and possible future. These experiments will be a part of an …

Hydrogen Fuel Cells, Sydney Pilgrim, Skyler Smith
ENERGY Research and Lesson Plans
Hydrogen fuel cells are hydrogen powered energy sources. They convert chemical energy into electrical energy by separating water molecules into the two elements that make up water, Hydrogen (2) and Oxygen (1). Hydrogen fuel cells are looking to become a paramount energy producer to avoid consuming fossil fuels for power. Along with the abundance of Hydrogen in the atmosphere being a benefit of using Hydrogen powered fuel cells, the only emission from these energy sources is water vapor. Many car engines only operate at a 20% fuel efficiency, whereas fuel cell powered cars utilize 60% of the energy produced. Although …

ENERGY Research and Lesson Plans
Two middle school science teachers collaborated with Georgia Southern lab students to conduct research and experimentation on the benefits of utilizing a dual-axis solar tracking system to assess the amount of voltage received during various times of the day. A smaller similar dual-axis solar tracking system was designed and fabricated to utilize in the teachers’ middle school classrooms in the study of renewable energy and the engineering and design process.
