| Abstract: | For Xeset 2 hydropower station in Laos,the main penstock has an inner diameter of 3m,connected to 2 branch pipes of 1.6 m inner diameter each by Y bifurcated pipe.Due to greater HD value of bifurcated pipe,its structure is analyzed and optimized by 3D finite element method on the basis of analytical calculation specified in standards,and rational shape of Y bifurcated pipe is proposed. |
