Non-monotonic behavior of the Binder Parameter in the discrete spin systems
Hiroshi Watanabe, Yuichi Motoyama, Satoshi Morita +1
We study a non-monotonic behavior of the Binder parameter, which appears in the discrete spin systems. We show that the Binder parameters of the Potts model are non-monotonic for $…
Effects of polymers on the cavitating flow around a cylinder: A Large-scale molecular dynamics analysis
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
The cavitation flow of linear-polymer solutions around a cylinder is studied by performing a large-scale molecular dynamics simulation. The addition of polymer chains remarkably su…
Kobayashi--Warren--Carter type systems with nonhomogeneous Dirichlet boundary data for crystalline orientation
Salvador Moll, Ken Shirakawa, Hiroshi Watanabe
In this paper we study the Dirichlet problem for the Kobayashi--Warren--Carter system. This system of parabolic PDE's models the grain boundary motion in a polycrystal with a presc…
Molecular Dynamics Simulation of Soundwave Propagation in a Simple Fluid
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
A molecular dynamics (MD) simulation was performed to study the propagation of soundwaves in a fluid. Soundwaves are generated by a sinusoidally oscillating wall and annihilated by…
Energy-dissipation in a coupled system of Allen-Cahn type equation and Kobayashi-Warren-Carter type model of grain boundary motion
Hiroshi Watanabe, Ken Shirakawa
In this paper, we consider a system of initial boundary value problems for parabolic equations, as a generalized version of the "-- model" of grain boundary motion, pro…
Effects of Cavitation on Karman Vortex Behind Circular-Cylinder Arrays
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
The effects of cavitation on the flow around a circular-cylinder array are studied by using a molecular dynamics simulation. Cavitation significantly affects on vortex shedding cha…
