摘要

A systematic investigation has been conducted to study liquid oxygen (LOX) droplet gasification and dynamics in supercritical hydrogen streams. The formulation is based on time-dependent conservation equations of mass, momentum, energy, and species concentration in axisymmetiic coordinates, and accommodates thermodynamic nonidealies and transport anomalies at high pressures. The model allows a thorough examination of realistic droplet behavior during its entire life time, including dynamic deformation, droplet shattering, and secondary breakup. Results indicate that ambient flow strongly influences droplet evolution and as such changes the droplet gasification rate and dynamic characteristics. Detailed streamline patterns as well as contours of thermodynamic properties are studied to reveal mechanisms associated with droplet dynamics. A series of calculations has been performed to understand the effects of ambient flow on droplet gasification behavior. Consequently, correlations of aerodynamic drag coefficient and droplet lifetime are obtained as functions of ambient pressure and Reynolds number.
