Terminal settling velocity for binary irregularly shaped particle mixture from fluidization study: experiment, empirical correlation, and GA-ANN modeling

Sudipta Let et al.

Summary: This study investigated the settling velocities of solid particles in different liquid-particle systems under quiescent conditions, and proposed a correlation formula to estimate the settling velocities of a binary mixture of irregular-shaped particles. The study also utilized a hybrid of genetic algorithm and artificial neural network model to predict the settling velocities.

Improved Settling Velocity for Microplastic Fibers: A New Shape-Dependent Drag Model

Jiaqi Zhang et al.

Summary: A new shape factor and drag model were proposed in this study to predict the settling velocities of microplastic fibers more accurately, showing applicability to films and fragments as well. However, the new model appears deficient at reasonably predicting the terminal settling velocity of weathered microplastics in the field, requiring further investigations.

Terminal velocity and drag coefficient for spherical particles

Haim Kalman et al.

Summary: The study reviewed empirical correlations and experimental works on the relationship between drag coefficient (C-D) of spheres with Reynolds number (Re) and Re with Archimedes number (Ar), and found the best-fit correlations for experimental results. New correlations for Re-Ha and C-D-Ar were also established, with the latter being easier to use than the common C-D-Re curve.

A new model for the terminal settling velocity of microplastics

Zijian Yu et al.

Summary: In this study, the settling process of microplastic particles in water bodies was investigated, and a new formula for the drag coefficient and settling velocity of microplastic particles was developed. The new formula showed smaller errors and improved accuracy in predicting the motion behavior of microplastics.

On the prediction of settling velocity for plastic particles of different shapes

Simona Francalanci et al.

Summary: The transport processes of plastic particles in freshwater and marine environments are important for predicting the fate of plastic in the environment. By studying the effect of different shapes on settling velocity, a new method was developed to predict the settling velocity of plastic and natural particles across a range of flow regimes. Calibration and validation with experimental data support the application of this method in various hydraulic conditions.

A new model for settling velocity of non-spherical particles

Fan Yang et al.

Summary: Settlement of non-spherical particles in riverine ecosystems is commonly observed and influenced by both particle and fluid properties. By collecting and studying 828 settling data, a new drag law for non-spherical particles has been developed, allowing for the prediction of settling velocity for particles of various shapes and materials. Further applications in hydrochorous propagule dispersal and sediment transport are projected based on a deeper understanding of the settling process.
