The research presented in this thesis includes the development of designs, materials, and fabrication processes and the results of characterization experiments for a meso-scale hydrogel-based lipid bilayer array system. ...
A Lean-Premixed Hydrogen Injector with Vane Driven Swirl for Application in Gas Turbines
(Virginia Tech, 2006-12-14)
Hydrogen, as an alternative to conventional aviation fuels, has the potential to increase the efficiency of a gas turbine as well as reduce emissions of greenhouse gases. In addition to significantly reducing the number ...
Particle Image Velocimetry Correlation Signal-to-noise Metrics, Particle Image Pattern Mutual Information and Measurement uncertainty Quantification
(Virginia Tech, 2014-08-14)
In particle image velocimetry (PIV) the measurement signal is contained in the recorded intensity of the particle image pattern superimposed on a variety of noise sources. The inherent amount of signal mutual information ...
Reduction of Unsteady Stator-Rotor Interaction by Trailing Edge Blowing Using MEMS Based Microvalves
(Virginia Tech, 1999-04-16)
This research performs an experimental study of a trailing edge blowing system that can adapt to variations in flow parameters and reduce the unsteady stator-rotor interaction at all engine operating conditions. The fan ...
A personal computer based instrumentation system for determining real-time dynamic torque in rotating machinery
(Virginia Tech, 1987-06-10)
<p>Measurement of dynamic/transient torques is important in the dynamic analysis of rotating machinery as it provides insight into the internal state of the machine. Existing methods are difficult to implement, results ...
The effect of solidity on the pre- and post-stall flow in a linear compressor cascade
(Virginia Tech, 1988-05-02)
<p>An experimental investigation of the performance characteristics of a solid wall linear compressor cascade was conducted. The purpose of the experiments was to determine the effects of the blade row configuration ...
Direct Measurement of Boiling Water Heat Flux for Predicting and Controlling Near Critical Heat Flux
(Virginia Tech, 2013-05-23)
A novel method for measuring heat flux of boiling water is designed and built to study critical heat flux (CHF) and observe the response of a heat flux sensor when CHF occurs. A high temperature heat flux sensor is embedded ...
