Modeling And Measurement Of Evaporation From Frequently Tilled Sandy Soils, Nicholas R. Lawson
Modeling And Measurement Of Evaporation From Frequently Tilled Sandy Soils, Nicholas R. Lawson
Electronic Theses and Dissertations
Moisture observation and control is the single largest factor that controls the mechanical properties of sand based surfaces used for thoroughbred horse racing. Currently the moisture content is estimated based on the experience and expertise of the superintendent and water is added as needed based on experience. While extensive modelling has been done on moisture loss from a range of soils with crop covers in agronomy, currently no method exists to estimate the evaporation from a surface that is tilled many times a day and remains in a partially compacted state. This thesis develops an evaporation model based on real …
Characterization Of A Wind Tunnel For Use In Offshore Wind Turbine Development With Mitigation Measures For The Wall Effect Of Proximal Structures, James Newton
Electronic Theses and Dissertations
This thesis supports the development of the Harold Alfond W2 Ocean Engineering Laboratory constructed at the University of Maine through several investigations conducted with a one-third scale wind generation system. The scale wind generator is first tested in what is considered an open-circuit wind tunnel configuration to determine the influence proximal building walls of a facility housing such a device may have on the consistency and capacity of a wind generator. Turbine performance testing with the wind generator to identify any susceptibility to proximal wall influence is also conducted. This is of interest as the full-scale system will operate …
Aerodynamic And Modal Analyses Of Small Scale Horizontal Axis Wind Turbine With Various Numbers Of Blade Design, Emile Maroha
Aerodynamic And Modal Analyses Of Small Scale Horizontal Axis Wind Turbine With Various Numbers Of Blade Design, Emile Maroha
Electronic Theses and Dissertations
With the global energy demand rising to unprecedented numbers, the need for alternative energy sources is ever prevalent. Wind energy is the most alternative renewable sources today due to its year-round availability and pollution-free nature. Horizontal Axis Wind Turbines (HAWT) are the most popular because of their higher efficiency. The aerodynamic characteristics and vibration of small scale HAWT with various numbers of blade design have been investigated in this numerical study in order to improve its performance. SolidWorks was used for designing CAD models, and ANSYS software was used to study the dynamic flow around the turbine as well as …
