Aerodynamic design considerations for small-scale, fixed-pitch, horizontal-axis wind turbines operating in class 2 winds.
(, 2012-08-08)Renewable sources of energy, such as wind, are necessary to meet the growing demand as conventional energy sources are depleted. Very little research has been accomplished to improve wind turbine performance in Class 2 ... -
Applying mass and energy balances to model series and parallel fan-powered terminal units.
(2015-07-31)Performance data from four manufacturers of fan-powered terminal units was analyzed and simple models of the fan/motor power use developed. These data included two fan motors: permanent split capacitor motors with silicon ... -
Assessment of shaped film cooling holes at high density ratios for gas turbine cooling using S-PIV and PSP.
(2016-02-27)During film-hole cooling, relatively cold air is extracted from the compressor of a gas turbine engine and forced through the turbine airfoils in order to lower their surface temperatures. To investigate the effects of ... -
Convective heat transfer from realistic ice roughness distributions.
(, 2013-09-16)As supercooled water droplets impinge the surfaces of in-flight aircraft, a layer of accreted ice will form. In the initial stages of the accretion process, the ice will form as a distributed surface roughness. Ice ... -
Converting coconut husks into binderless particle board.
(2009-04-01)Coconuts grow abundantly in tropical regions, and the coconut husk is often discarded as waste. However, a new application has increased interest in developing this previously underutilized resource. Coconut pith has ... -
Damage accumulation of bovine bone under variable amplitude loads.
(2016-01-15)Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study into damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear damage accumulation ... -
Design and experimental testing of small-scale wind turbines.
(2011-05-12)Due to the increasing environmental and economic cost of fossil fuels, alternative sources of energy are needed. One such source is energy wind energy. Much of the current wind turbine research focuses on large-scale wind ... -
Design and implementation of a synthetic aperture radar (SAR) imaging system using an ultra-wideband (UWB) radar sensor.
(2016-04-14)This thesis documents the design and implementation of a radar imaging system. A rail system was constructed to control the location of an off-the-shelf ultra-wideband (UWB) radar along a linear path. Range imaging, ... -
The design and validation of an impinging jet test facility.
(2006-05-28)An experimental jet impingement facility was constructed with the capability of conducting a detailed analysis of the local heat transfer coefficients beneath an array of large impinging jets. The facility was validated ... -
Design and validation of new testing apparatus for testing helical compression springs under combined axial, shear, torsion, and bending loads.
(, 2011-09-14)Helical compression springs are normally used to provide a linear force response to compressive displacement. However, compression springs can be used to provide lateral force and rotational torque responses to lateral and ... -
Designing, constructing, and testing a second-generation prototype mechanical hippotherapy horse.
(, 2011-09-14)The use of horses as a means of therapy has been documented for some time. To determine why this type of therapy works and to provide a means of expanding its accessibility, a mechanical horse has been developed. Data ... -
The effect of roughness element thermal conductivity on turbulent convection.
(2011-05-12)Many flows of engineering interest occur over surfaces that exhibit roughness with thermal conductivities much lower than common metals and alloys. This is especially true of in-service gas turbine blades with surface ... -
Effects of nozzle geometry and extrudate swell on fiber orientation in Fused Deposition Modeling nozzle flow.
(2015-07-31)Fused Deposition Modeling (FDM) is a rapidly growing Additive Manufacturing (AM) technology using extruded thermoplastics to produce intricate three-dimensional parts from digital data. Adding discrete fibers to FDM filament ... -
