Optical Measurements in Gas-Liquid Stirred Tanks

The thrust of this research is to provide innovative, in-situ, optical techniques that can accurately obtain bubble dynamics in a G-L ST, readily track liquid level height to determine the volumetric expansion of CXLs, and determine the phase transition of fluids from the subcritical to the supercritical state – all across a wide range of operating pressures, temperatures, and fluids. The knowledge and understanding of optical probes and G-L STs as well as supercritical and dense phase reactors will be advanced, valuable knowledge for CFD modeling will be provided, and new engineering science will be generated in systems at elevated conditions never before reported in the literature.
