Computational Analysis of Microplastics Hydrodynamics
Summary
Researchers developed a numerical model in Python and OpenFOAM to simulate microplastic particle dynamics in laminar open-channel flow, finding that particles smaller than 0.5 mm are unlikely to settle regardless of sphericity index, with results validated on a supercomputer.
U ovom radu provedeno je istraživanje dinamike kretanja mikroplastike kroz laminarni tok vode u otvorenom kanalu. Početak rada utemeljen je na teorijskim saznanjima o mikroplastici. Nakon toga opisan je numerički model implementiran u Pythonu i uspostavio se numerički model unutar OpenFOAMa. OpenFOAM analize provedene su na superračunalu BURA i prikazana je usporedba Python i OpenFOAM numeričke analize. Rezultati modela potvrdili su odstupanja u vjerojatnosti taloženja čestica mikroplastike s obzirom na njihov indeks sferičnosti i naglašena je vjerojatnost da čestice manje od 0,5mm bez obzira na indeks sferičnosti, teško dostižu dno domene.

Modeling the settling and resuspension of microplastics in rivers: Effect of particle properties and flow conditions
Researchers developed a mathematical model to simulate how microplastics of different shapes settle and resuspend in rivers, moving beyond the common assumption that all particles are spherical. They found that turbulence has a complex effect, sometimes keeping particles suspended longer and sometimes accelerating their settling, depending on flow conditions. The model reveals that particle shape significantly influences where microplastics end up in river systems.
