Abstract

By creating coherent flow structures at the vane tips of a headbox in a controlled manner it was shown that these coherent flow structures could be traced all the way from the slice chamber to paper. In addition, a correlation between the coherent structures and the structural cockling tendency of paper was found. Thus, important complementary information was created to serve the goal of finding a general linkage between structures in flow and paper.
