Particle deposition in fully-developed turbulent pipe flow is quantified taking into account uncertainty in electric charge, van der Waals strength, and temperature effects. A framework is presented for obtaining variance-based sensitivity in multiphase flow systems via a multi-fidelity Monte Carlo approach that optimally manages model evaluations for a given computational budget. The approach combines a high-fidelity model based on direct numerical simulation and a lower-order model based on a…

Brownian particle deposition in a directly simulated turbulent channel flow
Diffusion of submicron particles in a simulated turbulent channel flow field is studied. The turbulent flow velocity field is generated by a direct numerical integration of the Navier–Stokes equation
Direct numerical simulation of dense particle-laden flows using a conservative immersed boundary technique
Dense particle-laden flows are challenging to model because of their inherent multiphysics and multiscale nature. In order to improve our understanding of these flows and develop efficient simulation
