The prediction of the terminal velocity of non-spherical particles, such as sediments and
microplastics, is essential for understanding their transport processes in rivers or marine
environments. However, most of the existing models have been proposed based on specific
particle materials, and there is a lack of systematic research on the effects of different shape
factors on terminal velocity. In this study, super-ellipsoidal particles were selected as test
particles for settling experiments, and a particle–velocity tracking code was developed to …
