Experimental investigation of particle-laden underexpanded jet flow
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-08-01

The fluid-structure interaction of an axisymmetric underexpanded jet flowing across an adjacent compliant surface
… of the relatively little-explored problem of an underexpanded axisymmetric jet flowing across an adjacent parallel surface, in both rigid-surface and compliant-surface configurations. To date, the vast majority of the literature for both the rigid- and compliant-surface cases has been generated …

High speed geological boundary layer flows
… eruption of 1980 which was hypothesized to be an underexpanded jet originally by Kieffer. Key questions include: What causes the transition that can be seen in the two blast zones of Mount St. Helens characterized by the blow down pattern of the trees? On the double-ejecta layer craters, what …

Experimental Measurements of Pressure, Temperature, and Density Using High-Resolution N(2) Coherent Anti-Stokes Raman Scattering
In the underexpanded jet flowfield, the experimental P/T/p measurements are compared to similar quantities extracted from a RANS CFD simulation. The agreement between the mean CARS measurements and CFD predictions along the jet centerline and radial traverses is generally excellent. This CARS …

A comprehensive analysis of natural gas direct injection and of mixture formation in spark ignition engines
… of the physical processes related to the jet formation and development and the formation of the air-fuel mixture. The results of the numerical analysis are then correlated with the outcomes of an experimental activity performed on the developed multi-cylinder engine and on an optical …

Fundamental physics and application of plasma actuators for high-speed flows
… energy was also applied to a sonic transverse jet in a supersonic cross flow. Lastly, the particle image velocimetry diagnostic was considered and a technique developed to evaluate measurement uncertainty and using experimental velocity data to solve for density from the continuity equation. In …
