摘　　要：基于粒子图像测速技术(PIV)研究了分银炉内侧吹、底吹、顶吹3种喷吹方式的速度场分布及湍流动能。结果表明,在所有喷吹气量下,顶吹喷吹时熔池搅拌混匀时间远长于侧吹与底吹。底吹喷吹熔池平均运动速度相对于侧吹喷吹高25%~105%。对比底吹与侧吹,底吹喷吹下湍流动能远远大于侧吹喷吹,侧吹湍流动能为400~500数量级,而底吹湍流动能为10万~百万数量级。Experimental study on distribution of the velocity field and turbulence kinetic energy in silver melting furnace based on particle image velocimetry was carried out for3kinds of injection modes The results show that,under all the injection volume investigated,then molten pool immersion time of top blown is far higher than that of side blown and that of bottom blown Comparing the average speed of molten pool,bottom blown is25%to105%higher than side blown In comparison between bottom blown and side blown,the turbulence kinetic energy under bottom blown can be far greater than that of side blown,the turbulence kinetic energy under side blown is400to500orders of magnitude,and the turbulence kinetic energy under bottom blown is100000to millions of orders of magnitude
