【摘要】 本文采用积分方程法对带副叶片的混流式转轮的Sl 流面进行了流场计算。在将多连域化为单连域时采用了在副叶片头部作割线的方法 ,并采用主、副叶片的库塔条件作为补充方程。本文推导出多连域的积分方程公式 ,编写了计算程序 ,给出了算例 ,并得到了合理的结论。更多还原

【Abstract】 In this paper,the Integrated Method is used for the calculation of S i streamline surface of Franceis turbine with half vanes.The multiply connected domain is transformed into the simply connected domain with secants being attached on the head of the half vane,and the enforcing Kutta condition upon the double vanes is joined into the equational group.The content of the paper as following:the Integrated Equation formula is developed,the program is compiled,a calculation example is run and the conclusion is reasonable.更多还原
