1.
The hydraulic performance of the full spiral casing,with three typical rule of the variable area given,is analyzed through the simulation applied the Navier-stokes equations and the standard k-ε turbulent close equations.
本文基于N-S方程和标准k-ε紊流模型,用数值模拟的方法分析了三种典型的面积变化规律对全蜗壳水力性能的影响。
2.
Aimed at the defects present in conventional hydraulic design method of full spiral casing,the hydraulic design of spiral casing with non-circular section,in which the flow observes constant velocity-moment law was analyzed and approached.
针对水轮机全蜗壳常规水力设计方法中存在的不足,对蜗壳中水流遵循速度矩为常数规律运动的非圆形断面水力设计进行分析,利用数值计算方法,使蜗壳尾部圆断面内的水流遵循速度矩为常数的运动规律,而无需转换成椭圆断面,从而完善蜗壳非圆形断面的水力设计方法。
