Abstract
Fan nozzle is the core component of tool cooling system, but the study on spray characteristics of the nozzle is not deep enough. Solid Works model of fan nozzle was established in this paper, the injection characteristics of nozzle are simulated by FLUENT analysis. Influence law of the injection characteristics of fan nozzle was studied by changing some parameters of fan nozzle spray in the process, such as liquid viscosity, nozzle flow, operating pressure and surface tension. The simulation results show that in the case of other parameters are the same, the higher the operating pressure is, the higher the jet velocity of fan nozzle is, the jet diffusion of fan nozzle along a flat direction increases firstly and then decreases; The higher the liquid surface tension is, the smaller the jet diffusion of fan nozzle along a flat direction, but the influence of liquid surface tension to the jet velocity of fan nozzle outlet can be neglected.
