The collective dynamics of self - propelled particles
We have proposed a method for the dynamic simulation of a collection of self-propelled particles in a viscous Newtonian fluid. We restrict attention to particles whose size and velocity are small enough that the fluid motion is in the creeping flow regime. We have proposed a simple model for a self-propelled particle, and extended the Stokesian Dynamics method to conduct dynamic simulations of ...
متن کاملCollective dynamics of self-propelled particles with variable speed.
Understanding the organization of collective motion in biological systems is an ongoing challenge. In this paper we consider a minimal model of self-propelled particles with variable speed. Inspired by experimental data from schooling fish, we introduce a power-law dependency of the speed of each particle on the degree of polarization order in its neighborhood. We derive analytically a coarse-g...
متن کاملCollective Dynamics of Self-propelled Semiflexible Filaments
The collective behavior of active semiflexible filaments is studied with a model of tangentially driven self-propelled worm-like chains. The combination of excluded-volume interactions and selfpropulsion leads to several distinct dynamic phases as a function of bending rigidity, activity, and aspect ratio of individual filaments. We consider first the case of intermediate filament density. For ...
متن کاملStabilization of Collective Motion of Self-Propelled Particles
This paper presents analysis and design of feedback control laws for stabilization of parallel and circular trajectories of a network of self-propelled particles. Timescale separation of inter-particle alignment and spacing controls permits application of previous convergence results for oscillator phase synchronization and particle motion.
متن کاملCollective motion of rod-shaped self-propelled particles through collision
Self-propelled rods, which propel by themselves in the direction from the tail to the head and align nematically through collision, have been well-investigated theoretically. Various phenomena including true long-range ordered phase with the Giant number fluctuations, and the collective motion composed of many vorices were predicted using the minimal mathematical models of self-propelled rods. ...
