Electron emission thermal energy conversion
(University of Missouri--Columbia, 2010)
Electron emission from a surface can be achieved via two mechanisms: tunneling and thermionics. Converting thermal energy to electrical power using these mechanisms is achieved by generation of an electron current from the ...
An axisymmetric interfacial tracking model for melting-vaporization-resolidification in a thin metal film irradiated by pico to femtosecond pulse lasers
(University of Missouri--Columbia, 2010)
A two dimensional axisymmetric, interfacial tracking method is developed to model rapid melting and solidification of a free standing metal film subjected to an ultra-short laser pulse. Finite volume method is employed to ...
Wettability and nanostructure effect on oscillating heat pipes
(University of Missouri--Columbia, 2015)
As electronics technologies rapidly develop with a demand for more power and miniaturization, effective thermal management of these systems becomes much more important. The oscillating heat pipe (OHP) is a promising highly ...
Development and experimental benchmarking of numeric fluid structure interaction models for research reactor fuel analysis
(University of Missouri--Columbia, 2015)
As part of the Global Threat Reduction Initiative (GTRI) reactor conversion program, five U.S. High Performance Research Reactors (HPRRs) are currently studying a novel Low Enriched Uranium (LEU) foil based fuel to replace ...
Saddle point of attachment in horseshoe vortex system
(University of Missouri--Columbia, 2015)
Laminar juncture flow has been well studied experimentally and numerically in recent years. New topology upstream in terms of saddle point of attachment has been investigated by both approaches. In this work, the obstacle ...
Analysis of dual-phase ejector performance

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An analytical model is proposed to extend the single-phase model for predicting ejector performance, particularly pressure recovery and efficiency, ...
A parametric evaluation of carbon nanotube synthesis from alumina particles
(University of Missouri--Columbia, 2015)
Carbon nanotubes (CNTs) are a new material which was first discovered in 1991, and they have generate huge activities in most science and engineering areas due to their unprecedented electrical, thermal, and mechanical ...
Two-phase flow over flooded micro-pillar structures with engineered wettability
(University of Missouri--Columbia, 2013)
Flooding caused by excessive droplet feeding on heat dissipation areas periodically occurs for droplet-based thermal management. The conventional highly wettable texture of target surfaces, which is designed for thin film ...
Robust control design for a proportional valve with backlash compensation
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work, a linear technique is used to study the stability of a nonlinear system. Most of dynamic systems in industrial and fluid power systems ...
Factors affecting oscillating motion and heat transfer in an oscillating heat pipe
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] As demand has grown for thermal management solutions, interest in passive heat transfer devices such as heat pipes has grown as well. In particular, ...
New tool design for measuring tool displacement in milling
(University of Missouri--Columbia, 2012)
Monitoring tool displacement during a milling process allows the operator to identify when there is relative movement between the cutting tool and the workpiece. When the relative movement between the cutting tool and the ...
Plasmonic Au nanostructures for surface-enhanced raman spectroscopy
(University of Missouri--Columbia, 2013)
Raman spectroscopy is a spectroscopic technique that provides rich structural information for identifying chemical species but finds limited applications owing to its low sensitivity. Surface-enhanced Raman spectroscopy ...
