摘要
用有限元法计算径流式叶轮机械蜗壳的紊流时均流场.有关紊流模型采用K-ε两方程模型,用关于压力p的罚函数方法求解.所得结果可供分析蜗壳流场用.文中方法也可用于计算其他形状的二维通道流动.
In this paper study the mean turbulent flow in a scroll of the radial turbomachine. The K- Eeqs. model and panalty method are applied in turbulence calculation. The results may be used to analyse the flow field in the scroll. This method can also be used to calculate the 2-dimensional turbulent flow in the channel.
