Abstract

A small UDOG was developed and tested over a range of geometries and operation conditions. Analysis and numerical modelling were used to characterize uniform droplet oxygen generators. The numerical model included mass, momentum, energy conservation equations for the droplets and gas, and species rate equations for the gas, gas-liquid interface, and liquid phase chemistry. A relatively simple analytical model was also developed to allow solution of the equations which govern chlorine and O₂(¹(Delta) ) concentrations in the reaction zone. Measurements were made of most inflow and outflow properties, including the O₂(¹(Delta) ), O₂(¹(Sigma) ), Cl₂, and H₂O concentrations. The chlorine utilization, O₂(¹(Delta) ) yield, and generator efficiency were measured as affected by several parameters. Predicted dependencies were observed over a wide range of test conditions. The UDOG efficiency was significantly higher than has been achieved by the other generator types, when compared at the laser cavity condition.
