High Speed Photography and 3-D CFD Simulation of Pulsed Anti-riots Water Cannon Launch Process
In order to study the atomization mechanism of gas-liquid two-phase flow,high speed camera was used to photo the water-jet,the jet images at different time were gained,CFD technology was used to simulate the launch process of water cannon in 3-D Model,Large Eddy Simulation and VOF model were used to describe the turbulent flow and track the gas-liquid interface in and out of launch pipe.The gas-liquid distribution image of experiment and simulation,water-jet velocity of experiment and simulation both matched well with other.The simulation results show that the flow pattern in launch pipe of water cannon changed from atomization pattern to annular pattern and finally slug pattern,the conclusion has significant meaning to the study of second spray and first atomization of water-jet.
