Abstract

This paper aims to study the deposition and dispersion of nano-particles in turbulent tubular
pipe flows. In this work, the Eulerian-Lagrangian particle tracking method is used to simulate the
transport of nano-particles in turbulent flows under the conditions of one-way coupling. In order to
simulate the turbulent flow in a pipe, the Reynolds stress transport model (RSTM) is used with the
help of CFD method. RSTM is one of the most accurate Reynolds-averaged Navier-Stokes methods.
In addition, near wall region, Two-layer zonal model is employed in the CFD model to simulate the
viscous sublayer separated from the fully-turbulent layer in the pipe. The results show that RSTM
with Two-layer zonal model can well predict the turbulent flow and particle deposition velocity in
tubular pipes. The output of this study can provide a guideline for evaluating the nano-particle
transport and deposition in turbulent pipe flows.
