摘　　要：为了核算涡轮设计方案,评价设计结果的优劣,优化涡轮气动特性.从多级联算的角度,采用多重网格技术,在静、动叶之间利用"混合平面"方法对高温气冷堆氦气轮机的六级涡轮进行了三维黏性流场计算分析.结果表明,无论总体参数还是叶列间参数计算值与设计结果均吻合较好,并且经分析发现导叶采用了"后部加载"叶型,使涡轮具有了优良的变工况气动性能.此外,计算结果还暴露了原设计中尚存在一些不足,为进一步优化该涡轮的叶型指出了方向,经改进后涡轮性能可能达到更高水平.To prove a turbine＇s initial design,evaluate the design result,and optimize the turbine＇s aerodynamic performance,three-dimensional（3-D） viscous multistage CFD analysis was conducted on a helium turbine of a high temperature gas-cooled reactor（HTGR-HT）,employing a multi-grid and mixing the plane method between the rotor blade and guide vane.The 3-D analysis result shows that not only the overall parameters but also parameters between stage rows agreed well with the initial design,and perfect performance was achieved under different working condition by using an aft-load blade profile in the stator blade.Moreover,the 3-D calculation result indicates some disadvantages in the original design,thus giving reference for optimizing the blade profile to achieve even better helium turbine performance.
