Abstract
This paper presents a method for integrating two-phase flow into the vector formulation of the One-Dimensional Turbulence model (ODT) without the introduction of any additional free parameters into the model. ODT is an unsteady turbulent flow simulation model implemented on a one-dimensional domain, representing flow evolution as observed along a line of sight through a 3D turbulent flow. Overturning motions representing individual eddies are implemented as instantaneous rearrangement events. Particles are simulated in a turbulent channel using one-way coupling.
Numerical simulations were run with turbulent friction Reynolds numbers, Reτ, 180 and 640. Validation was achieved by comparing wall-normal profiles of particle statistics with DNS, LES, and experiments.
