This article reports a study in which drag coefficient is defined more comprehensively. The coefficient is defined as a function of particle nominal diameter, gravitational acceleration, the ambient fluid kinematic viscosity, and the particle shape. This new definition is different from the conventional definitions proposed in the literature based on direct equations as a function of particle Reynolds number. The conventional definitions appear to be a simplification of drag coefficient and… 
Improved drag coefficient and settling velocity for carbonate sands
TLDR
This work presents a new approach to estimating the drag coefficient of carbonate sands that considers both friction and pressure and demonstrates that even small differences in the settling velocity obtained with the new drag coefficient can lead to substantial changes in sediment transport.
Can terminal settling velocity and drag of natural particles in water ever be predicted accurately?
Abstract. Natural particles are frequently applied in drinking water treatment processes in fixed bed reactors, fluidised bed reactors, and sedimentation processes to clarify water and to concentrate
Can terminal settling velocity and drag of natural particles in water ever be predicted accurately?
Natural particles are frequently applied in drinking water treatment processes in fixed bed reactors, fluidised bed reactors, and sedimentation processes to clarify water and to concentrate solids.
Study of the effect of particle size and mixture on sediment formed in the solid-liquid separation process in polymeric fluid through the gamma-ray attenuation technique
ABSTRACT Drilling fluids behave as shear-thinning and thixotropic fluids and present cuttings and solid additives. Understanding the sedimentation of these solid elements is important to avoid
Grain shape effects in bed load sediment transport
Bed load sediment transport, in which wind or water flowing over a bed of sediment causes grains to roll or hop along the bed, is a critically important mechanism in contexts ranging from river
Impact of nearshore vegetation on coastal dune erosion: assessment through laboratory experiments
The primary objective of this study was to delineate the impact of vegetation on dune erosion under the influence of storm waves. This was achieved through laboratory flume experiments. Specifically,
Numerical Investigation of Freely Falling Objects Using Direct-Forcing Immersed Boundary Method
The fluid-structure interaction of solid objects freely falling in a Newtonian fluid was investigated numerically by direct-forcing immersed boundary (DFIB) method. The Navier–Stokes equations are

Closure of discussion on Drag coefficient and fall velocity of nonspherical particles
The most commonly encountered particles in the areas of sediment transport, fluidization, sedimentation, etc. are nonspherical. The role of these particles can be ascertained only through the
