Numerical Simulation Research on Water Atomization in Oil Flow
Based on a new method to produce fluid ice,water atomization in an immiscible oil flow is simulated numerically in this paper.Considering surface tension and gravitational force effects,a set of three-dimensional transient conservation equations of mass and momentum are established.Within these equations,the coupling between pressure and velocity is solved by using the Pressure Implicit Splitting Operators (PISO) algorithm.Based on the volume-of-fluid (VOF) method,the multi-dimensional Piecewise Linear Interface Construction (PLIC) technology is applied to trace the behavior of water-oil interface movement.The flow situation under multiple working conditions is simulated.Results show that the average atomization diameter of water droplets increases with the velocity of water and decreases with the velocity of oil,and it also increases with the diameter of atomization nozzle.
