Abstract

Binary droplet collision under high ambient pressures was investigated numerically by using the front tracking method. The particular interest of the investigation is to predict the kinetic energy dissipation of droplet bouncing, which tends to be the dominant collision outcome in the impinging sprays under high ambient pressures. A practically useful model was proposed based on the predicted kinetic energy dissipation and implemented in the KIVA-3V computer program code for the Lagrangian simulation of the free and impinging spray experiments under high ambient pressures. The results show that the model can make qualitatively satisfactory predictions to the spray shape, the tip penetration length, and the Sauter mean diameter.
