A Transient Electromagnetic Flowmeter, Paul J. Lefebvre, William W. Durgin
A Transient Electromagnetic Flowmeter, Paul J. Lefebvre, William W. Durgin
Office of the Provost Scholarship
An electromagnetic flowmeter was developed to measure transient flows with a frequency response of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics of a commercially available electromagnetic flowmeter normally used for steady-state operation. Use of the commercially available flowmeter body, which includes the magnetic coils, core, and signal electrodes, provided a relatively economical means of fabricating the transient flowmeter. A transient flow calibration facility consisting of a free-falling water column was also designed and built. Results of the calibrations are presented and show that the flowmeter can accurately measure transient flows up to the …

Radiant Energy Transfer And Radiant Barrier Systems In Buildings, Florida Solar Energy Center, Philip Fairey
FSEC Energy Research Center®
In Florida and other southern climates we depend on a number of strategies to keep heat out of buildings. Mostly, these affect heat gains by conduction or convection. In the average house, insulating walls and ceilings primarily restricts conduction. Double-glazed windows restrict both conductive and convective heat gain. We have largely ignored radiation - the third means of heat transfer - except in using window treatments and coatings that reflect, absorb or shade from solar energy. But research points to exciting potential for reducing heat gain in buildings by controlling radiation transfer in walls and ceilings through the use of …

Techniques For Shading Residential Walls And Windows, Florida Solar Energy Center, Philip Fairey
FSEC Energy Research Center®
Solar radiation is a major heat source in buildings - welcome in cold weather but a summertime problem. Florida's long cooling season and short heating season increase the importance of protecting windows, walls and sliding glass doors during hot weather, while still permitting solar heat to enter a building during cold weather. cooling and heating energy savings of 10% - 20% are possible through good shading strategies. Properly designed roof overhangs can provide adequate sun protection, especially for south-facing surfaces. Vertical shading devices such as trees, trellises, trellised vines, shutters, shading screens awnings and exterior roll blinds are also effective. …

Solar ovens work much like solar collectors used in domestic water heating systems. Both collect solar radiation, convert it to heat and transfer it to another substance. Solar ovens, however, focus the sun's rays with reflective surfaces on one point. The object of the sun's energy in the solar oven is the food.

Shear Layer Coupling With Side-Branch Resonators, D. D. Erickson, William W. Durgin, C. F. Maguire Iii, M. J. Moeller
Shear Layer Coupling With Side-Branch Resonators, D. D. Erickson, William W. Durgin, C. F. Maguire Iii, M. J. Moeller
Office of the Provost Scholarship
High velocity flow past the junction of a side branch with a pipe can result in the excitation of depth-mode standing waves in the branch. The shear layer separating the main stream flow and the cavity provides coupling between the driving and the driven flow. Photographic evidence indicates that large scale vortex structures develop at the shear layer. The vortex formation process involves strongly non-linear instability of the shear layer and may be characterized as a non-linear fluid mechanical oscillator. The standing wave system formed in the cavity is essentially an acoustic wave system of nearly linear character. The principle …

The Mechanics Of Flycasting: The Flyline, Graig A. Spolek
The Mechanics Of Flycasting: The Flyline, Graig A. Spolek
Mechanical and Materials Engineering Faculty Publications and Presentations
In order to propel a fishing fly through the air toward the distant quarry, a rather massive line, to which the fly is attached, is cast. As the cast line rolls out, the fly actually accelerates horizontally and seems to defy physical law. The phenomenon is modeled simplistically to determine the magnitude of this effect. In the absence of air drag, the fly can accelerate to increase its velocity by an order of magnitude. Air friction dramatically decreases the effect, but some fly accelerationis still predicted. By tapering the flyline in various ways, the fly velocity history can be significantly …
Interpretation Of Venous Occlusion Plethysmography Using A Nonlinear Model, F. A. Anderson, Jr., William W. Durgin, H. Brownell Wheeler
Interpretation Of Venous Occlusion Plethysmography Using A Nonlinear Model, F. A. Anderson, Jr., William W. Durgin, H. Brownell Wheeler
Office of the Provost Scholarship
Venous occlusion plethysmography (VOP) is a noninvasive technique widely employed for the detection of deep-vein thrombosis. Previous reports that VOP outflow curves are closely fit by a first-order exponential suggest that venous compliance and resistance are nearly constant. Typically, however, the venous compliance function has a sigmoid shape; in addition, the resistance in a collapsing tube must increase. This paradox was resolved by the surprising finding that for realistic nonlinear compliance and resistance these nonlinearities cancel, producing a quasilinear venous outflow that approximates a simple exponential.

Mechanical Engineering Faculty Research
Some early history of ceramic applications is presented. Finite element modeling of components to determine service and fabrication loads found inelastic behavior and residual stresses to be significant to component life. Inelastic behavior mitigates peak strains but enhances residual strains. Results of furnace, Mach 0.3 burner, and engine tests are discussed and categorized into design criteria (loading, geometry, fabrication, materials, analysis, and testing). These design rules and finite element analyses are brought to bear on two test cases: turboshaft engine seals, and rocket thrust chambers.
