Primary breakup of coflowing gas and liquid sheets is an important fluid dynamics problem which can been seen in many industrial applications like fuel injection. A solid understanding of spray formation through fuel injection systems is vital to improve the energy utilization efficiency and pollution control. In the present work, large-scale three-dimensional simulations are performed to investigate the breakup of coflowing gas and liquid sheets, using 2,048 processors on the supercomputer. The simulation results reveal the complex multi-scale multiphase flow features that are originally unclear. The detailed formation of the droplets through the breakup of the liquid sheet can be clearly seen from the video.

Abstract
Primary breakup of coflowing gas and liquid sheets is an important fluid dynamics problem which can been seen in many industrial applications like fuel injection. A solid understanding of spray formation through fuel injection systems is vital to improve the energy utilization efficiency and pollution control. In the present work, large-scale three-dimensional simulations are performed to investigate the breakup of coflowing gas and liquid sheets, using 2,048 processors on the supercomputer. The simulation results reveal the complex multi-scale multiphase flow features that are originally unclear. The detailed formation of the droplets through the breakup of the liquid sheet can be clearly seen from the video.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
