Introduction

Fluid-particle interactions play a crucial role in various industrial processes and natural phenomena. This article explores the fundamental understanding of fluid-particle interactions, focusing on suspension rheology and particle transport. By investigating the behavior of particles suspended in fluids, researchers and engineers can optimize processes, improve material properties, and gain insights into complex systems [1]. This section discusses suspension rheology, which studies the flow behavior and material properties of particle-laden fluids. It explores the influence of particle concentration, size, shape, and surface properties on the rheological behavior of suspensions. The section highlights the importance of understanding the interactions between particles and the surrounding fluid, including particle-particle and particle-fluid interactions. It also addresses the measurement techniques and mathematical models used to characterize suspension rheology [2].
