CFD-DEM Study of Nanoparticle Deposition in Tubular Pipes
Résumé
This study investigates the nanoparticle deposition in a tubular pipe using Eulerian-Lagrangian approach with computational fluid dynamics coupled discrete element method. The fluid flow is modeled as laminar with a given parabolic velocity profile, having mean velocity of 1 m/s. The motion of particles is simulated using the Discrete Element Method (DEM), taking into account primary forces such as drag and Brownian. Two initial particle distribution cases are examined: particles injected as a flux at the inlet and particles uniformly distributed throughout the pipe. The study provides valuable insights into the deposition efficiency and the impact of initial particle distribution on the deposition process.
