AN EXPERIMENTAL STUDY OF PAPER FLUTTER

An experimental study was conducted in order to clarify the phenomenon of paper flutter. Flutter speed was measured in wind tunnel tests for sheet paper and web paper of various materials, sizes and tensions. The relationships between flutter speed, rigidity, mass ratio and tension were clarified from a large data set. The flutter boundaries were obtained in the form of dimensionless flutter speed and mass ratio for the case of sheet paper, and dimensionless flutter speed, mass ratio and tension parameter for the case of web paper. The flutter mode and air-flow around fluttering paper were investigated by visualization tests.
