Experimental investigation of overall effectiveness and coolant jet interactions on a fully cooled C3X turbine vane
… measurements focused on investigating row-to-row interactions of coolant jets and the contributions of external film cooling and internal impingement cooling to overall cooling effectiveness. Overall effectiveness was experimentally measured using a thermally scaled, matched Biot number vane model …

Scaleable nanomanufacturing of metasurfaces using microsphere photolithography
… to focus collimated light to nanoscale photonic jets in a photoresist layer. This dissertation investigates the fabrication capabilities, process control, and potential applications of MPL. First, the MPL concept is applied to the fabrication of metasurfaces with engineered IR absorption (e.g. …

Mult-Scale Jet/Front Interactions that Organize Typical Cloud Seeding Environments in the Sierra Nevada
Jet/Front systems that propagate every winter season across the Pacific Ocean basin create a favorable environment for supercooled cloud water above the complex terrain over the Central Sierra Nevada Mountains. This environment favors cloud seeding which can enhance the local orographic …

In-Cylinder Soot Oxidation in an Optically Accessible Automotive Diesel Engine
… is how fuel injection conditions as well as jet-swirl and jet-jet interactions impact soot oxidation process. In this regard, various optical/laser-based imaging diagnostics were performed to unveil the development of high-temperature reaction and soot in small-bore optical diesel engines, …

Understanding the development of a reacting fuel jet inside an automotive-size diesel engine using optical and laser-based diagnostics
The fuel penetration and reacting diesel jet development have been studied in a small-bore optical engine to improve the understanding of a swirl-influenced, wall-interacting diesel flame. The optical access to the engine combustion chamber was made possible via multiple quartz windows positioned …

Internal Fluid Dynamics and Frequency Characteristics of Feedback-Free Fluidic Oscillators
In this work, the internal fluid dynamics and frequency characteristics of feedback-free fluidic oscillators are investigated experimentally and numerically. The internal flow field of various scale oscillators was extracted using a refractive index-matched Particle Image Velocimetry (PIV) …
