Abstract

High-pressure droplet interaction of liquid oxygen vaporization in a gaseous hydrogen environment is studied. A one-dimensional single droplet vaporization model is used, and the droplet interaction is treated by the "droplet in bubble" model, which assumes an isolated elastic bubble surrounding the liquid droplet This work is based on the transient conservation equations and assumes constant pressure in the ambience. In addition, thermodynamic equilibrium is assumed at the droplet interface. The thermodynamic non-ideality and dissolution of gaseous hydrogen into liquid oxygen are taken into account. All physical properties, such as enthalpy and binary mass diffusivity, are estimated properly. The effects of ambient temperature and ambient pressure on the droplet interaction are studied. It is found that the ambient pressure has strong influences on the behavior of droplet interaction through both the heat and the mass transfer rates at the droplet interface. The mass transfer rate is the major mechanism controlling the droplet interaction at the late part of the droplet lifetime.
