Dynamics of a Bottom-Heavy Janus Particle Near a Wall Under Shear Flow

TL;DR

This paper investigates the behavior of a bottom-heavy Janus particle near a wall under shear flow, focusing on its dynamics and the influence of shear rate on particle motion.

Contribution

It provides a detailed analysis of Janus particle dynamics near a wall under shear, incorporating recent findings and clarifying the role of shear rate and noise assumptions.

Findings

Shear flow significantly affects particle orientation and position.

White noise assumptions are valid under certain shear conditions.

The Peclet number is clarified in relation to Brownian diffusion.

Abstract

After our attention was brought to recent work by Pelargonio and Zaconne regarding the deviation of the white noise function for systems at very large shear, we have included the work as a reference of interest to our readers and clarified the definition of our Peclet number with respect to the Brownian diffusion of the particle as well as included a brief discussion of the magnitude of our shear rate compared to the bath frequency to clarify that the standard white noise applies in our system.
