Model For Polygonal Hydraulic Jumps
Erik A. Martens, Shinya Watanabe, Tomas Bohr
We propose a phenomenological model for the polygonal hydraulic jumps discovered by Ellegaard et al., based on the known flow structure for the type II hydraulic jumps with a "roll…
Integral methods for shallow free-surface flows with separation
Shinya Watanabe, Vachtang Putkaradze, Tomas Bohr
We study laminar thin film flows with large distortions in the free surface using the method of averaging across the flow. Two concrete problems are studied: the circular hydraulic…
Row-switched states in two-dimensional underdamped Josephson junction arrays
Mauricio Barahona, Shinya Watanabe
When magnetic flux moves across layered or granular superconductor structures, the passage of vortices can take place along channels which develop finite voltage, while the rest of…
Averaging theory for the structure of hydraulic jumps and separation in laminar free-surface flows
Tomas Bohr, Vachtang Putkaradze, Shinya Watanabe
We present a simple viscous theory of free-surface flows in boundary layers, which can accommodate regions of separated flow. In particular this yields the structure of stationary…
Resonances of dynamical checkerboard states in Josephson arrays with self-inductance
M. Barahona, E. Trias, T. P. Orlando +4
We study the dynamics of fully frustrated, underdamped Josephson arrays. Experiments reveal remarkable similarities among the dc current-voltage characteristics of several kinds of…
Stability of periodic solutions in series arrays of Josephson junctions with internal Capacitance
Shinya Watanabe, James W. Swift
A mystery surrounds the stability properties of the splay-phase periodic solutions to a series array of N Josephson junction oscillators. Contrary to what one would expect from dyn…
