ClearEffect of hydrocyclone design in microplastics-water separation by using computational fluid dynamics simulations
Researchers used computer fluid dynamics simulations to test and optimize the design of hydrocyclones — spinning funnel-shaped devices that use centrifugal force to separate particles from water — for removing microplastics, finding an optimized geometry that achieved 76% microplastic recovery. The results show that carefully tuning the proportions of a hydrocyclone's components can significantly improve its ability to filter microplastics from water at scale.

Researchers used computer fluid dynamics simulations to test how the size of a hydrocyclone — a cone-shaped device that uses spinning water to separate particles — affects its ability to remove microplastics from water.
