The Effect of Sensitization on the Stress Corrosion Cracking of Aluminum Alloy 5456
(Monterey, California. Naval Postgraduate School, 2012-06)
This work examines the effect of sensitization on the stress corrosion cracking behavior of marine grade aluminum alloys (Al-Mg). These alloys can be sensitized during operation, promoting their susceptibility to intergranular ...
Real-time dynamic model learning and adaptation for underwater vehicles
(Monterey, California: Naval Postgraduate School, 2013-09)
Precision control of unmanned underwater vehicles (UUVs) requires accurate knowledge of the dynamic characteristics of the vehicles. However, developing such models are time and resource intensive. The problem is further ...
Design, test, and evaluation of a transonic axial compressor rotor with splitter blades
(Monterey, California: Naval Postgraduate School, 2013-09)
A new design procedure was developed and documented that uses commercial-off-the-shelf software (MATLAB, SolidWorks, and ANSYS-CFX) for the geometric rendering and analysis of a transonic axial compressor rotor with splitter ...
Fabrication and Optimization of Carbon Nanomaterial-Based Lithium-Ion Battery Anodes
(Monterey, California. Naval Postgraduate School, 2012-03)
Lithium-ion batteries possess high energy and power densities, making them ideal candidates for energy storage requirements in various military applications. Commercially produced lithium-ion battery anodes are commonly ...
Investigation of transitional flows on compressor blades in cascade
(Monterey, California. Naval Postgraduate School, 2011-09)
Flow around polished second-generation controlled-diffusion blades in cascade set at their design inlet flow angle was investigated at various Reynolds numbers using static pressure measurements, five-hole probe surveys, ...
Low-speed wind tunnel flow quality determination
(Monterey, California. Naval Postgraduate School, 2011-09)
lected points. Incorporated instrumentation includes pressure transducers attached to a pitot-static tube, wall static pressure taps, and a pressure rake; a hotwire anemometry system, and a linear traverse system. These ...
Electrical ship demand modeling for future generation warships
(Monterey California. Naval Postgraduate School, 2013-06)
The design of future warships will require increased reliance on accurate prediction of electrical demand as the shipboard consumption continues to rise. Current U.S. Navy policy, codified in design standards, dictates ...
Passive regeneration: long-term effects on ash characteristics and diesel particulate filter performance
(Monterey California. Naval Postgraduate School, 2013-06)
Diesel particulate filters (DPF) have seen widespread growth as an effective means for meeting increasingly rigorous particle emissions regulations. There is growing interest to exploit passive regeneration of DPFs to ...
Cooling system design tool for rapid development and analysis of chilled water systems aboard U.S. Navy surface ships
(Monterey California. Naval Postgraduate School, 2013-06)
Over the last several decades, there has been a dramatic increase in the complexity and power requirements of radars and other combat systems equipment aboard naval combatants and this trend is expected to continue for ...
Processing, microstructure, and material property relationships following friction stir welding of oxide dispersion strengthened steels
(Monterey, California: Naval Postgraduate School, 2013-09)
A comprehensive set of processing, microstructure, and material property relationships is presented for friction stir welded oxide dispersion strengthened MA956 steel. Eight rotational and traverse speed combinations were ...
