A simple, one-dimensional model of an intermittent flow is developed for interpretation of the previously observed effect of hydrodynamic regime rearrangement in a near wake from two cylinders subject to glow discharge. When the cylinders are not spaced too closely, the wake may be assumed to be formed by two von Karman streets. The model is distinguished by an account for the nonlinear interaction of the von Karman streets in the domain of their generation near cylinders; when, the assumption of weak interaction is not applied. Within the framework of the model, in combination wih one-frequency modes of the wake there exists an asymmetric two-frequency mode in a certain domain of the model parameters. In the turbulent wake, this mode and a symmetric mode are observed in intermittent regime between them.
