III:5 Flow in stratified headboxes
|
|
|
In production of multiply paper, three plane jets meet close to the outlet of the head box.
The fibre suspension of the middle jet is not the same as in the outer jets. Differences
in density, viscosity and velocity possibly cause an instability and undesired mixing
of the jets. This project study possible actions for avoiding mixing, possibly by changing
the geometry of the headbox or properties of the suspension.
