摘　　要：金属漆粘度值高,含金属颗粒,长时间放置出现液体分层现象,影响配色准度。为对搅拌器内金属漆进行充分搅拌,使金属漆达到较高均匀度,采用k-ε湍流模型和多重参考系模型(MRF),基于CFD(计算流体动力学)技术对不同搅拌桨组合下的金属漆搅拌器进行数值模拟。数值模拟结果表明,上层搅拌桨选择错位45°折叶涡轮桨叶,下层搅拌桨选择错位平直桨叶的搅拌器搅拌桨组合,与普通双层平直桨叶搅拌器相比搅拌效果更好,混合效率提高20.99%。The viscosity of metallic paint is high,containing metal particles,and the phenomenon of liquid stratification appears after long time storage,which affects the color matching accuracy.In order to fully stir the metallic paint in the agitator and make the metallic paint more uniform,the turbulence model and multiple reference frame model(MRF)are used to simulate the metallic paint agitator with different impeller combinations based on CFD(Computational Fluid Dynamics).The numerical simulation results show that the combination of the upper impeller with 45°staggered folded blade turbine blade and the lower impeller with staggered straight blade is better than the ordinary double-layer straight blade impeller,and the mixing efficiency is increased by 20.99%.
