摘要

Abstract

For engineering applications ofwater dilution controlling system

the fluid dynamics of a mixed flowwas studied with computational fluid dynamics (CFD) simulations and self-designed experimental set-up. In order to examine the predictability of CFDmodel for the headbox in industrial scale

two pulp suspensions beforemixingwere treated as homogeneous flows separately. Standard

k-ε

turbulence models with the mass diffusion in turbulent flows-species transport approach were applied in the simulations. A numerical simulation of this headbox model was analyzed with semi-implicit method for pressure linked equations scheme with pressure-velocity coupling. Results show that themodel can predict hydrodynamic characteristics of headbox with injecting dilution water in a central diffusion tube

and the distribution of water content at the outlet of the slice lip is ideally normal at different speeds.
