Abstract

The headbox is heart of the paper machine in paper industry. In the paper, the flow dynamics of the dilution water that adjusts the consistency of the fluid in a hydrodynamic headbox was studied by performing computational fluid dynamics (CFD) simulations. A standard k-ε turbulence model was used in conjunction with a study of the mass diffusion in the turbulent flow based on the species transport approach. A numerical simulation of headbox was performed using a SIMPLE scheme for the pressure-velocity coupling. The simulation results show that when dilution water was injected at different sites above the inlet of the step diffusion tube, the water content at the outlet of the slice channel conformed to a standard normal distribution. Furthermore, the site at which the dilution water is injected strongly affects the turbulent kinetic energy.
