An Electrochemical Impedance Spectroscopic Diagnostic Device for Characterization of Liquid-Liquid Systems and Phase Separation Detection in EmulsionsDownload
Rapid characterization of complex fluids, especially sensing emulsion stability, is crucial for many industrial applications, ranging from pharmaceutical industry to petroleum production. Electrochemical impedance spectroscopy (EIS) is a powerful tool for electrical characterization of such...
Characterization and Control of Cyclic Variability in a Gasoline/Natural Gas Dual-Injection Spark Ignition EngineDownload
Reducing the cyclic variability of a gasoline/natural gas dual injection spark ignition engine using minimum variance control is the subject of this thesis. Cylinder pressure is used to calculate four combustion metrics, the standard deviation of which is used as an indicator of cyclic...
The result of adding an insulation ring to the interior of the Diesel oxidation catalyst on pressure drop and light-off characteristics is investigated by injecting a ceramic material into the channels of the monolith forming a circular ring. The steady state pressure drop is recorded as a...
A dual-fuel system is used to control HCCI combustion timing and load in a CFR engine. The systems steady-state response to iso-octane and n-heptane injected energy is investigated then a dynamic ARMAX model is found using system identification. This model is used to design a norm-optimal...
The ability to control large vortices in the wake of an unsteady body is studied experimentally. A single airfoil in a uniform flow is forced to oscillate sinusoidally about its aerodynamic center and the resulting wake is expected to be dominated by large coherent vortices The wakes for several...
This thesis is an experimental investigation using optical methods to study atomization of fuel injectors for IC engines using a dual fuel mixture involving diesel and gasoline blends, which is called "dieseline". Experiments were executed in a heated pressurized optical chamber which simulated...
