Theses and Dissertations
Renewable production of water, hydrogen, and power from ambient moisture
(Monterey, California: Naval Postgraduate School, 2016-12)
This thesis developed a concept design and prototype system capable of increasing and improving the main energy constraints the Department of Defense must overcome to meet future mission requirements, energy availability ...
Stall analysis in a transonic compressor stage and rotor
(Monterey, California. Naval Postgraduate School, 2009-06)
Gas turbine engine design is based on simplifying assumptions, including axi-symmetric flow. These assumptions break down in the real machines especially when operating near to stall. The reduction in operating surge ...
Development and Analysis of a Bi-Directional Tidal Turbine
(Monterey, California. Naval Postgraduate School, 2012-03)
The concept of using renewable energy for power generation has experienced much attention with increasing costs of non-renewable sources. The largest untapped renewable energy resource is in the form of the oceans and ...
Development of a MEMS-Scale Turbomachinery Based Vacuum Pump
(Monterey, California. Naval Postgraduate School, 2012-06)
This study forms part of a larger study to develop a MEMS scale turbomachinery based vacuum pump. This would allow very high vacuum to be drawn for handheld mass spectroscopy. This thesis concentrates on the roughing portion ...
Experimental investigation of high-pressure steam induced stall of a transonic rotor
(Monterey, California. Naval Postgraduate School, 2007-06)
Steam leakage from the catapult system of U.S. Navy aircraft carriers can stall the compressors of modern jet aircraft if ingested during takeoff. This phenomenon, known as "pop stall", is of particular concern to the U.S. ...
Flow field survey in a transonic compressor rig
(Monterey California. Naval Postgraduate School, 2006-06)
As the Navy prepares to transition to F-35C Joint Strike Fighter the need to understand "pop stalls-- caused by steam leakage in catapult systems is of concern. â Pop stalls* caused by steam ingestion through the aircraft ...
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 ...
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, ...
Computational fluid dynamic model of steam ingestion into a transonic compressor
(Monterey, California. Naval Postgraduate School, 2009-06)
The U.S. Navy's concern with steam-induced jet engine stall has become more pertinent with the introduction of the F-35C. During take offs on aircraft carriers, steam from aging catapult systems can potentially seep onto ...
UPGRADE TRANSONIC COMPRESSOR TEST RIG DATA ACQUISITION SYSTEM
(Monterey, CA; Naval Postgraduate School, 2018-06)
This thesis presents an upgraded data acquisition system (DAS) for the transonic compressor test rig (TCR). The legacy DAS acquired and processed pressure, temperature, and rotational speed data. The data were mass averaged, ...
