In wet-lab experiments, the slime mold Physarum polycephalum has demonstrated its ability to tackle a variety of computing tasks, among them computation shortest paths and design efficient networks. For path problem, mathematical model for evolution is available it been shown in computer experiments through analysis that dynamics solves problem. this paper, we generalize network We formulate as...

Flow networks can describe many natural and artificial systems. We present a model for flow system that allows volume accumulation, includes conduits with nonlinear relation between current pressure difference, be applied to of arbitrary topology. The displays complex dynamics, including self-sustained oscillations in the absence any dynamics inputs outputs. In this work we analytically show or...

In the context of longitudinally boost-invariant Bjorken flow with transverse expansion, we use three different numerical methods to analyze emergence attractor solutions in an ideal gas massless particles exhibiting constant shear viscosity entropy density ratio $\eta / s$. The fluid energy is initialized using a Gaussian profile plane, while $\chi = \mathcal{P}_L \mathcal{P}_T$ between longit...

A series of experiments on stratified Taylor–Couette flow in short aspect ratio wide-gap annuli found an intriguing and not-well-understood dynamics: nonlinear coherent structures appearing disappearing periodically, along with density layering reminiscent staircase profiles. detailed numerical study is presented the dynamics near onset instability this setting, which explains most characterist...

The dynamics of chemically-powered self-propelled nanodimer motors in a fluid flow are investigated. The dimer motors are confined to move in a square channel within which a Poiseuille-like fluid flow exists. The flow direction is opposite to that of the nanomotor’s directed motion. Simulations of the dynamics are carried out using mesoscopic hybrid molecular dynamics/multiparticle collision dy...
