This study aims to determine the dynamics of a spherical particle that is suspended in a fluid that is confined between two parallel moving walls. A simulation was done using the molecular dynamics software LAMMPS. It was observed that the particle tends to move toward the wall nearer to it and that its equilibrium displacement is approximately proportional to its initial distance from the center. It was also observed that increasing the wall velocity increases the magnitude of this lateral displacement.
