Flagmill -A new power generator utilizing flexible sheet-
Journal of Fluid Science and Technology, 2015 The present study proposes “a flagmill”, which is a new power generator utilizing the flutter of a flexible sheet such as a flag. The sheet flutter causes the angular oscillation of the supporting pole. Since the supporting pole is connected to the power
