The pressure distribution of noncavitating potcnial flow around gate piers shown in Fig. la has been analysed. The analysis has its practical significance in that the minimum-pressure coefficient is closely related to the incipient cavitation number. After the W plane was mapped on to, the t plane with known transformations except an unknown parameter m, the complex velocity was expressed by Eq. (10) in terms of an unknown function Ω (t). Eqs. (13) and (16) indicate that along the boundary f and g are respectively related, to the magnitude of the boundary velocity and the boundary geometry. Three equations to solve for the three unknowns are furnished by the conditions along the boundary: (1) The angle τ is given as a function of z. (2) f and g, being the real and imaginary parts of an analytic function, are related to each other. (3) The points of tangency are transformed to points on the real axis of the t plane. For the case in which the nose curve is composed of circular arcs, Eqs. (22), (28) and (29) were derived. The functions f and g were found numerically by iteration, and m was computed from Eq. (28). The distribution of velocity and that of pressure along the line of symmetry and the boundary were computed and plotted in Fig. 5, in which the pressure distribution from wind tunnel tests was also included. Preliminary results on incipient cavitation number were plotted in Fig. 6, to be compared with the theoretical |C_(pm)| curve. More tests are being done to study the scale effects.

The paper proposes a model for optimal load flow calculation in which the real and imaginary parts of all the node voltages are used as state variables. The basic idea is as follows: By aid of Zangwill penalty method, the optimal load flow problem is transformed from a constrained optimization problem into a sequential unconstrained optimization problems which are solved by the BFS (Broyden-Fletcher-Shanno) method. The BFS method possesses better numerical stability so that the high precision of uni-dimensional search is unnecessary. Therefore, the guadratic interpolation that needs smaller amount of calculation can be used as uni-dimensional search technique. Thus the amount of calculation of the method is decreased,and the convergence can be quaranteed sufficiently. Finally the effectiveness of the method is proved by the given examples.

本文提出用全部节点电压实部和虚部作为状态定量的最优潮流计算模型。基本思路是:通过Zangwill罚函数法将最优潮流问题由一个约束优化问题变为一序列的无约束优化问题,然后用BFS(Broyden-Fletcher-Shanno)法求解。由于BFS法的数值稳定性较好,对一维搜索精度要求不高,因此可以采用计算量较小的二次插值作一维搜索。这样计算工作量有所减少,而收敛性又可以得到充分保证。最后用实例证实了该方法的有效性。
