Fall 2021
Motivated by relevant applications in spray cooling, coating, and inkjet printing, droplet impact dynamics on a solid surface is investigated both numerically and experimentally by varying several major control parameters such as impact velocity, contact angle, and surface temperature. First,...

Spring 2013
In this thesis, ultrasonic B-scan signal processing is investigated. A B-scan displays a cross-sectional view of the test piece and defects within it. Compared to A-scan signals, B-scan images offer more reliable fault detection. Nonetheless, traditional ultrasonic signal processing methods are...

Uncertainty in Life Cycle Assessments of Well-to-Wheel Greenhouse Gas Emissions of Transportation Fuels Derived from Various Crude Oils
DownloadFall 2016
Growing concern over climate change has created pressure on the oil and gas industry to reduce their greenhouse gas (GHG) emissions. Several life cycle assessment (LCA) studies have examined various crude oils in an attempt to determine which have the lowest and highest well-to-wheel (WTW) GHG...

Unsteady characteristics of three-dimensional turbulent flow with separation in an asymmetric diffuser
DownloadFall 2017
A great number of studies have been undertaken to understand separated turbulent boundary layers (TBLs) due to its importance in the performance, design and control of many engineering systems (Hal 2000). Flow separation has a complicated three-dimensional nature in many flow configurations...
