An experimental investigation on the characteristics of the liquid sheet formed by the impingement of two capillary liquid jets was conducted. The focus of the study was on the liquid instabilities that occurred at the edges of the sheet. This work first identified three breakup regimes of the liquid sheet, and then focused on the capillary breakup regime, where a stable closed-rim sheet existed. The distribution of fluid velocity on the sheet was examined. In addition, the dimensional characteristics of the sheet were studied and new equations were derived for the thickness and shape of the sheet. The breakup of the droplets from the edges of the sheet was investigated by using direct visualization. The process of generating droplets was divided into two stages: growing stage and detaching stage. Detailed analysis was provided. Theoretical and experimental studies were completed to find the distribution of the sheet edge velocity.

An imaging technique is used to investigate the fluid dynamics associated with the breakup of a liquid jet by a passing transverse shock wave. This mechanism is believed to be a potential source of combustion instability in liquid propellant rocket engines. Combustion instability is caused by the release of heat in phase with a passing pressure disturbance. The jet/wave interaction causes rapid atomization and propellant redistribution, and enhances mixing, vaporization, and reaction rates. Knowledge of the breakup process aids in prediction of local heat release with respect to the passing wave and provides insight on its viability as a potential instability mechanism. The present shock tube study applies high-speed, high-resolution photography to explore the jet/wave interaction that might be experienced in a large scale liquid oxygen/hydrogen (LOX/H2) engine similar to the Space Shuttle Main Engine (SSME) or other such engines being considered for the next generation of launch systems. Fluid parameters deemed important were simulated as well as possible. Two types of wave induced breakup were examined: a constant velocity flow field (square wave) and an exponentially decaying velocity field (N-wave). Time resolved images of the jet/wave interaction indicate very rapid and fire atomization within 500 microns of impingement. Shock interaction with the primary atomization process produces a substantial change to the breakup mechanism and serves as a principal candidate for the promotion and acceleration of rocket engine instability. Results of the qualitative and quantitative study reveal that the step wave produces a long duration tangential and normal stress on the liquid column as compared to the N-wave. As a result, N-waves decelerate jet displacement and extend the jet breakup time.

Capillary Flows with Forming Interfaces explores numerous theoretical problems that arise in the mathematical description of capillary flows. It focuses on developing a unified approach to a variety of seemingly very different capillary flows of practical importance where classical fluid mechanics leads to nonphysical results.
