Kink Solution in a Fluid Model of Traffic Flows
Shigeaki Wada, Hisao Hayakawa
Traffic jam in a fluid model of traffic flows proposed by Kerner and Konhäuser (B. S. Kerner and P. Konhäuser, Phys. Rev. E 52 (1995), 5574.) is analyzed. An analytic scaling solut…
Nonequilibrium phase separation in traffic flows
H. Hayakawa, K. Nakanishi
Traffic jam in an optimal velocity model with the backward reference function is analyzed. An analytic scaling solution is presented near the critical point of the phase separation…
Behavior of fluidized beds similar to equilibrium states
Kengo Ichiki, Hisao Hayakawa
Systematic simulations are carried out based on the model of fluidized beds proposed by the present authors [K.Ichiki and H.Hayakawa, Phys. Rev. E vol.52, 658 (1995)]. From our sim…
Two Hydrodynamic Models of Granular Convection
Hisao Hayakawa, Daniel C. Hong
We present two continuum models A and B to study the convective instability of granular materials subjected to vibrations. We carry out the linear stability analysis for model A an…
Thermodynamic Theory of Weakly Excited Granular Materials
Hisao Hayakawa, Daniel C. Hong
We present a thermodynamic theory of weakly excited two-dimensional granular systems from the view point of elementary excitations of spinless Fermion systems. We introduce a globa…
