Fluid Flow and Structural Analysis for the Design of Portable Microplastic Collection System
Summary
Researchers evaluated the separation performance of four cyclone system designs for a portable microplastic collection device, testing their ability to separate microplastic particles of 10, 50, and 100 µm from sand under fluid flow conditions. They found that a single-chamber internal structure achieved the highest separation efficiency, with improved performance for particles larger than 50 µm, and that structural analysis confirmed safety factors exceeding 1.5 for all integrated components.
본 연구에서는 휴대용 미세플라스틱 분리장치에서 중요한 역할을 하는 사이클론 시스템의 성능을 평가하였으며 사이클론 분리장치가 미세플라스틱과 그 내부로 유입되는 모래를 얼마나 잘 분리하는지 살펴보았다. 분리성능 평가에 사용된 사이클론은 총 4가지이며, 4가지 사이클론 중에서 단일 내부 구조를 가진 형태가 분리 성능 측면에서 가장 높은 효율을 가지는 것으로 확인되었고, 또한 10, 50, 100 μm 크기의 미세플라스틱 입자 크기에 대한 분리 성능을 평가하여 50 μm 크기보다 큰 입자 크기에서 분리 성능이 향상됨을 확인하였다. 그리고 휴대용 미세플라스틱 포집 시스템의 작동에 따른 구조적 안정성을 평가하기 위해 사이클론 시스템과 일체화된 흡입구, 분리구, 토출구에 대해 구조 해석을 수행하여 안전률 1.5를 상회하는 결과를 얻었다.

Cyclone Shapes for Sand and Microplastic Separation: Efficiency and Reynolds Number Relationships
This study compared three cyclone separator designs for their ability to separate microplastics from beach sand, finding that a cone-shaped design achieved near-perfect efficiency for denser plastic types but lower efficiency for lightweight Styrofoam. Cyclone-based separation offers a promising mechanical approach for cleaning microplastics from coastal sediments at scale.

Effect 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.
Optimising miniaturised hydrocyclones for enhanced separation of microplastics
Researchers optimized the design of miniaturized hydrocyclones for separating small microplastics in the 5-20 micrometer range from water. Using computational fluid dynamics simulations, they identified optimal inlet geometry and flow conditions that significantly improved particle separation efficiency. The study demonstrates that mini-hydrocyclones could serve as a compact and energy-efficient technology for removing very small microplastics from water treatment systems.
