Stability and spatial autocorrelations of suspensions of microswimmers with heterogeneous spin

Stability and spatial autocorrelations of suspensions of microswimmers with heterogeneous spin

In this paper, suspensions of active swimmer-rotor particles have been mathematically modeled by extending a previously developed stochastic kinetic theory to analyze heterogeneous collections of microswimmers and microrotors with multiple spin velocity populations. The paper uses this modeling appr...

description In this paper, suspensions of active swimmer-rotor particles have been mathematically modeled by extending a previously developed stochastic kinetic theory to analyze heterogeneous collections of microswimmers and microrotors with multiple spin velocity populations. The paper uses this modeling approach to derive insight on large-scale properties, such as suspension instabilities and spatial correlations of the active particles, and highlights the role of active particle rotations on the behavior of the suspension. A secondary aim is to demonstrate an analytical approach for understanding the emergence of patterns that have been observed for self-propelled micro-particles using numerical and lab experiments.
