| Abstract: | In order to meet the requirement of improving the efficiency of the steam turbine, a low pressure exhaust hood design optimization system is constructed by integrating software as SolidWorks, ICEM and CFX based on the SiPESC.OPT platform. The optimization of one type of low pressure exhaust hood is performed on the SiPESC.OPT platform by using various methods such as the parametric modeling, three-dimensional viscous fluid analysis, and ant colony algorithm. The result shows that the average pressure recovery coefficient has increased 188.31% and the no-uniform coefficient of the steam flow at the outlet has decreased after the optimization. In addition, the result indicates that the optimization can effectively improve the pneumatic performance of the turbine's low pressure exhaust hood. |
