Geometric phase of spheroidal particles in a fluid flow and its control

TL;DR

This paper explores how spheroidal particles in a fluid flow experience geometric phases in both position and orientation, and demonstrates methods for controlling and targeting these particles within the flow.

Contribution

It introduces the concept of geometric phases in spheroids' position and orientation and presents control strategies for their manipulation in fluid flows.

Findings

Geometric phases occur in both position and orientation of spheroids.

Control and targeting of spheroidal particles are achievable within the flow.

The study provides a framework for manipulating particles using geometric phase principles.

Abstract

We investigate the dynamics of spheroids immersed in the journal bearing flow subject to a contractible non-reciprocal loop. We show how geometric phases appear not only in the position, but also in the orientation of such particles. We show how control and targeting can be carried out on spheroidal particles in the flow.
