Modeling Autophoretic Microswimmers
Analysis
This paper presents a new numerical framework for modeling autophoretic microswimmers, which are synthetic analogues of biological microswimmers. The framework addresses the challenge of modeling these systems by solving the coupled advection-diffusion-Stokes equations using a high-accuracy pseudospectral method. The model captures complex behaviors like disordered swimming and chemotactic interactions, and is validated against experimental data. This work is significant because it provides a robust tool for studying these complex systems and understanding their emergent behaviors.
