In recent years, the method of Lindstedt and Poincare for the periodic solution in celestial mechanics and theory of non-linear oscillation has been extended to the problem of stability of fluid motion. It is called the theory of bifurcation. It is interesting to see if the method of Krylov and Bougolubov in the theory of non-linear oscillation could also be applied to this problem.In the present paper, the latter method is applied to the problem of stability of plane Poiseuille flow to investigate the...

In recent years, the method of Lindstedt and Poincare for the periodic solution in celestial mechanics and theory of non-linear oscillation has been extended to the problem of stability of fluid motion. It is called the theory of bifurcation. It is interesting to see if the method of Krylov and Bougolubov in the theory of non-linear oscillation could also be applied to this problem.In the present paper, the latter method is applied to the problem of stability of plane Poiseuille flow to investigate the existence and stability of the periodic solution near the neutral curve. Results are compared with those of [2, 3] and are found to be in excellent agreement. However, unlike bifurcation theory, the method of present paper can also be used in the study of transient and other problems.

近年来,天体力学及非线性振动理论中的Lindstedt和Poincaré求周期解的方法,被推广应用于流动稳定性问题,形成了分支(Bifurcation)理论。可以设想,非线性振动理论中的和渐近法,也可被用于这一问题。 本文以平面Poiseuille流为例,试用渐近法研究其中性曲线附近的周期解及其稳定性问题,和已知的分支理论结果进行比较,在这一问题上,二者是一致的。但本文方法不仅可用于研究周期解,且可研究过渡过程及其他问题。

A new approach is proposed in the application of the Krylov-Bogouliubov method, which is the generalization of the formulation given by J. T. Stuart, to the problem of stability of plane Poiseuille flow in the subcritical range. The deficiency of the so-called 'false problem' method due to Reynalds and Potter is discussed. Some results of computation are presented. The calculated threshold amplitudes for R=5000 and 4000 with different frequencies are compared with Nishioka's experimental observations,...

A new approach is proposed in the application of the Krylov-Bogouliubov method, which is the generalization of the formulation given by J. T.

Some results of computation are presented. The calculated threshold amplitudes for R=5000 and 4000 with different frequencies are compared with Nishioka's experimental observations, the results are encouraging. Further, the perspective of the possible application of the method for analysing the resonant triad in the subcritical range has also been pointed out.

文中给出了一种将J.T.Stuart所发展的弱非线性稳定理论用于亚临界情况下平面Poiseuille流的新方法。论述了Reynalds和Potter的理论的缺点。给出了一些计算结果,井把R=5000及R=4000时各种频率下的扰动阀值和Nishioka的实验结果进行了比较。结果是不错的。还论述了将该法用于研究形成内共振的三个扰动波的可能性。

In [1], Zhou proposed a new approach to deal with the nonlinear stability problems of plane Poiseuille flow in the sub critical range. In this paper, the proposed method is extended to problems of nonlinear strong interaction of a two-dimensional disturbance and a pair of three-dimensional disturbances (the so called resonant triad). In the subcritical case, there does not exista resonant triad in the strict sense. However, by extending the method proposed in [1]. we can also extend the idea of resonant...

In [1], Zhou proposed a new approach to deal with the nonlinear stability problems of plane Poiseuille flow in the sub critical range. In this paper, the proposed method is extended to problems of nonlinear strong interaction of a two-dimensional disturbance and a pair of three-dimensional disturbances (the so called resonant triad). In the subcritical case, there does not exista resonant triad in the strict sense. However, by extending the method proposed in [1]. we can also extend the idea of resonant triad, so we do find resonant triads in the subcritical case. It is also noted that there exists a certain mechanism which makes the proposed method conceptually reasonable.

在文献[1]中,周恒提出了一个研究亚临界(一般来说可为非临界)平面Poiseuille流的稳定性的非线性方法。在本文中,将推广该法,用于研究二维及三维扰动波的非线性强相互作用问题。具体说,是共振三波(Resonat triad)问题。在亚临界情况下,严格讲不存在共振三波。但推广文献[1]中方法后,我们也可以推广共振三波概念,从而在亚临界情况下,找到了共振三波。文献中还指出,确实存在某种机制,使得本文方法不仅仅是一种单纯的数学处理方法。
