摘　　要：在已有探针的基础上,研制了新的能够同时测量汽轮机低压缸内湿蒸汽两相流流场、湿度、一次水滴和二次水滴的联合探针,通过FLUENT软件对结构进行优化,提出了一种新型的联合结构。数值模拟和风洞标定结果都表明对称结构的探针在气动性能上优于非对称结构。A new integrated probe is developed on the basis of existing probes.It can be used for measuring simultaneously all parameters of wet steam flow in LP steam turbine.The new structure of the probe is optimized with CFD.Both results with numerical simulation and calibration in a open wind tunnel demonstrate that the symmetrical structure of probes is superior in non-symmetrical structure in aerodynamic performance.
