1. Analysis of surface topography of slice jet

Subjects
Headbox, Astrophysics::High Energy Astrophysical Phenomena, High Energy Physics::Experiment, Surface structure, Forming, Free jet, Slice jet, Surface topography
Abstract

In the papermaking process it is a well-known fact that the flow condition of a free jet entering the former section has a direct influence on the structure of the final paper. In this paper we present a systematic analysis how surface roughness and MD characteristic size of the slice jet depend on jet velocity, jet length, pulp consistency and vane geometry. The measurements are based on laser profiling and ccd-imaging.
