摘　　要：以镁合金熔炉内的保护气体流动为研究对象,在细管喷嘴初始入口压力0.2MPa,出口直径3mm的情况下,采用计算流体力学软件Fluent,应用标准κ-ε方程湍流模型,研究了保护气体在熔炉内的流动特性。Taking the flow of protective gas in magnesium alloy furnace as a research object, when the thin tube nozzle in the initial inlet pressure was 0.2 MPa and the outside diameter was 3ram, the flow characteristics of the protective gas in the furnace were studied by using computational fluid dynamics software Fluent, with the application of the standard κ-δ equation turbulent model.

关 键 词：镁熔体 喷嘴 数值模拟 FLUENT
