摘要
根据流函数的变分原理 ,应用有限元方法对叶轮机械内部流场进行了求解 ,并应用变域变分的方法对叶栅下游周期性自由尾涡面进行了计算。理论计算与实验结果进行比较 ,结果表明理论计算和实验结果是相互吻合的。图 4参
In the present paper, the finite element method is applied on the variational principle of stream function. And the function variation domain is used for the treatment of the votex sheet at the trailing edges of the blade. Accordingly, a new method for handing the boundary conditions is worked out. The flow field in straight blades is also calculated, which is well in agreement with experiment results. Figs 4 and refs 3.
