LES Simulation of Near-field Spray Process and Atomization Characteristics of Impulse Anti-riots Water Cannon
Through Computational Fluid Dynamic(CFD) simulation method, One-Equation Large Eddy Simulation(LES) model coupled with the bounded and compressed VOF method was used to simulate the near-field of impulse antiriots water cannon for the study of its operational properties and application. The . instantaneous isosurfaces of liquid-phase volume fraction and the . high-speed photographs were compared. They are agreed with each other in the spray configuration and jet penetration length. The spray process is divided into three phases: liquid column burst, secondary burst, liquid film rupture. The inflation of the highpressure gas is considered to be the most dominant factor in the near-field. The influence of initial conditions on the atomization characteristics was investigated by condition-changing simulation. The conclusions provide guidance for further study and its operational application.
