摘要:
为了研究无刷励磁机在整流盘与转子间增加机座环板结构对流场涡流尺寸的影响,建立了无刷励磁机的整机流场的物理模型,基于流体动力学原理( CFD) ,采用有限体积法,在计算域内对三维湍流流场进行了数值求解,得到了额定转速时,增加机座环板后,无刷励磁机内部各部分流场分布特点。结果表明,整流盘与转子间增加机座环板结构,有效减少了检修空间处的大涡流尺度范围。与现运行方案的计算结果相比,该方案的入口体积流量增加了 13. 89% ,结果准确。为进一步优化该励磁机冷却风路系统提供了理论依据。
Abstract:
To study deeply the influence of the frame ring plate increased between rectifier wheel and rotor on the size of eddy current of fluid field of brushless exciter,the fluid field of complete brushless exciter model is established. Based on the computational fluid dynamics ( CFD) principles ,the finite volume method is adopted to simulate and analyze the three dimensional turbulent flow field in the computational domain. The distribution character of the fluid field for the brushless exciter is obtained under rated speed,after increasing the frame ring plate between rectifier wheel and rotor. The results show increased the frame ring plate between rectifier wheel and rotor can decrease effectively the size of eddy current in the air region between rectifier wheel and rotor. Compared with the result of running scheme,the air volume flow rate of the scheme has increased 13. 89% and the result is accuracy. It provides theoretical basis for further optimizing the air ducts structure of the brushless exciter .
