Numerical Simulation of Atomization Performance for Double-spout Nozzle Used in MQL Grinding
摘要
Abstract
In order to reduce the impacts of gas barrier,a double-spout nozzle was proposed.The atomization mechanism of MQL was analyzed,and the mathematical model was established by two-stage atomization model.The atomization process of the double-spout nozzle was simulated to analyses the atomization properties,and experiments were carried out to verify the simulation.The results show that the structure of the double-spout can effectively decrease the diameter of droplets and im-prove the atomization performance.The droplets sprayed by the assistant j et can break the air barrier layer and reduce the effect of the gas barrier layer on droplet flow.Therefore,the droplets from the main j et can enter the grinding zone easily.关键词
