# A note on forces exerted by a Stokeslet on confining boundaries

## TL;DR

This paper analyzes the forces exerted by a Stokeslet near confining boundaries and estimates the hydrodynamic pressure from force-free self-propelled particles in such environments.

## Contribution

It provides explicit calculations of boundary forces due to a Stokeslet and applies these to estimate pressures from active particles near walls.

## Key findings

- Calculated forces exerted by a Stokeslet on flat and parallel walls.
- Estimated hydrodynamic pressure contributions from self-propelled particles.
- Provided analytical tools for understanding boundary interactions in viscous flows.

## Abstract

We consider a Stokeslet applied to a viscous fluid next to an infinite, flat wall, or in-between two parallel walls. We calculate the forces exerted by the resulting flow on the confining boundaries, and use the results obtained to estimate the hydrodynamic contribution to the pressure exerted on boundaries by force-free self-propelled particles.
