A MODEL FOR NUMERICAL SIMULATION OF BREAKUP OF A LIQUID JET IN CROSSFLOW

Ravi K. Madabhushi
United Technologies Research Center, East Hartford, Connecticut, USA

ABSTRACT

A model has been developed for the numerical simulation of liquid jet atomization in a subsonic crossflow. The proposed model simulates the effects of jet bending and penetration prior to column fracture, droplet secondary breakup due to aerodynamic forces, changes in droplet drag due to distortion during breakup, and droplet dispersion due to gas-phase turbulence and drop breakup. The model has been implemented into a computational fluid dynamics (CFD) code, and coupled gas–droplet analysis has been applied to simulate the spray structures produced by the atomization of water jets injected into subsonic crossflows at several momentum ratios. Computed droplet size, velocity, and volume flux distributions have been compared with experimental data. The model captures the observed trends in volume flux profiles as the jet-to-air momentum flux ratio changes.
