(TU Delft Fluid Mechanics) Tummers, M.J. (TU Delft Fluid Mechanics) Westerweel, J. (TU Delft Fluid Mechanics) Date 2023 Abstract We report results on the instantaneous drag force on plates that are accelerated in a direction normal to the plate surface, which show that this force scales with the square root of the acceleration. This is associated with the generation and advection of vorticity at the plate surface. A new scaling law is presented for the drag force on accelerating plates, based on the history force for unsteady flow. This scaling avoids previous inconsistencies in using added mass forces in the description of forces on accelerating plates.
