GE 公司 E3 涡轮部件全三维流场计算与分析 曾军，王丽，王彬 中航工业燃气涡轮研究院610500 3 [ 摘 要 ] 采用全三维 CFD 软件 ANSYS CFX 分别对 GE 公司带冷气的 E 两级高压涡轮、五级低压涡轮 及共 14 排叶片的涡轮部件进行了全三维计算，湍流模拟采用带转捩模型 Shear Stress Transport （SST ）二方程模型。为了模拟气膜冷气喷射的影响，采用了源项模拟技术。计算 结果与试验值及部分设计值进行了对比，结果表明 CFX 软件对气冷多级涡轮流场模拟具有较 高的精度。通过研究掌握了 E3 发动机涡轮部件的设计特点和规律，为独立自主地开展先进民 用航空发动机涡轮部件的研制提供一定的参考和借鉴。 [ 关键词 ] 民用发动机，涡轮，CFD，湍流模型，转捩 Computed and analysis of full-3D flow of GE Energy Efficient Engine Turbine Components Zeng Jun ，Wang Li ，Wang Bin Avic Gas Turbine Establishment, 610500 [ Abstract ] Full-3D CFD simulation was carried out by commercial CFD software ANSYS CFX on a two-stage high pressure turbine and a five-stage low pressure turbine which including fourteen-row blades designed by GE. The source term method was used to simulate the film cooling of blades. The two-equation turbulence model SST with transition was selected to compute the turbulent flow. The computed data was compared particularly to the experiment data and design data. It shows that the CFX software has high accuracy on the flow fields of multi-stage cooling turbine. The design characteristic and rules of Energy Efficient Engine Turbine Components were obtained. It offered the reference for developing independently civil aviation engine turbine components.
