Improved DRW Model for Prediction of Deposition and Dispersion of Nano- and Micro-Particles in Turbulent Flows

Amir A. Mofakham, Goodarz Ahmadi
Proc. ASME. FEDSM2020, Volume 2: Fluid Mechanics; Multiphase Flows, V002T04A018, July 13–15, 2020
Paper No: FEDSM2020-20034
DOI: https://doi.org/10.1115/FEDSM2020-20034
... macroscale was proposed. It was shown that the new Improved-DRW model with the velocity and time scale drift corrections leads to uniform distributions for fluid- point particles and reasonable concentration profiles for finite- size particles. It was shown that the predicted deposition velocities...
