TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
For many applications involving liquid injection, the ability to predict the details of the breakup process is often limited due to the complexity of the two-phase phenomena. Likewise, the ability to experimentally characterize these phenomena is also limited due in part to the need to rely upon visualization tools which are inherently qualitative. As a result, the ability to validate predictions using these diagnostic tools is also limited. In recent years, visualization diagnostics have evolved substantially in terms of spatial and temporal resolution. The advancements, coupled with a tool to conveniently quantify the results obtained relative to the breakup process offer the potential for a marked increase in understanding of this phenomenon. The proposed effort will develop such a tool that will be applied to the problems of pressure swirl injectors and liquid injection into a crossflow. The typical characteristics associated with this type of liquid breakup, such as column/sheet flattening, bending, fracture point, dynamics, etc. will be automatically quantified using the tool proposed. The project will utilize existing results obtained with state-of-the-art high speed imaging, but will acquire limited data as well to validate the tools developed. Comparisons with advanced CFD modeling will be made to demonstrate the application of the software developed.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The project will result in a novel experimental technique that can be applied to existing and new imaging based diagnostic available at NASA. As applied to various two-phase flow problems, the tool developed will facilitate CFD validation as well as increased understanding of the breakup of liquids for a variety of applications. The tool is particularly well suited for quantitative comparison of experimental results with predictions from advanced simulation techniques such as LES and/or VOF or other high fidelity phase interface tracking methods. ERC will work closely with NASA to focus the Phase II efforts on areas/imaging problems of immediate interest to NASA.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The software developed will be of interest to imaging system providers to help improve the utility of their products. Likewise, any owner of such equipment applying it to problems involving sprays or multiphase flows can potentially make use of the software developed. Additional development for other specific applications will further expand the potential use.
