The unsteady force acting on a sphere that is held fixed in a steady uniform flow with small-amplitude oscillations is evaluated to 0 (Re) for small Reynolds number, Re. Good agreement is shown with the numerical results of Mei, Lawrence & Adrian (1991) up to Re = 0.5. The analytical result is transformed by Fourier inversion to allow for an arbitrary time… (More)
