Particles encountered in nature and engineering practice are normally not spherical but of
irregular shapes. Particle shape plays a key role in determining the behaviour of bulk solids …

Empirical correlations relating the drag coefficient of spheres to the Reynolds number are
qualitatively reviewed with the focus on the presumed mathematical expressions used in the …

Microplastics are ubiquitous pollutants within the marine environment, predominantly (>
90%) accumulating in sediments worldwide. Despite the increasing global concern …

In this work, a selection of widely used correlations have been critically evaluated for
estimating the drag coefficient of non-spherical particles in incompressible viscous fluids …

Microplastics (MPs) have been found in all terrestrial, marine, and riparian environments,
including remote regions. This implies that atmospheric transport is an important pathway …

The field of multiphase flows has grown by leaps and bounds in the last thirty years and is
now regarded as a major discipline. Engineering applications, products and processes with …

Microplastics are abundant in aquatic environments and are an emerging environmental
concern. The prediction of their settling velocities is central to predictions of the residence …

A simple formula to calculate the settling velocity of natural sediment particles for grain sizes
between 0.063 and 1 mm is presented. The formula has been derived from the previous …

An accurate correlation for the smooth sphere drag coefficient with wide range of
applicability is a useful tool in the field of particle technology. The present study focuses on …
