摘要
通过对结晶器搅拌桨的结构分析,以螺距比h/D,盘面比AE/AO和筒径比d/D′等为参数实现搅拌桨的参数化设计.以结晶器内各点流速均匀分布为原则,用通用流体力学分析软件Fluent对釜内流场进行了定量分析,确定最优参数为:h/D=1.2,AE/AO=0.7,d/D′=0.63.
Based on analyzing the structure of industrial crystallizer impellers, their parametric design was realized with pitch ratio h/D, blade area ratio AE/AO and draft tube-stir tank diameter ratio d/D′ as the basic parameters. Based on the principle that all points in a crystallizer have the same flow rate, a general purpose CFD (computational fluid dynamics) software Fluent was used in the quantitative analysis of the flow field in a crystallizer, and the optimization parameters was obtained, i.e. h/D=1.2, AE/AO=0.7 and d/D′=0.63.
