The force on a sphere in a uniform flow with small-amplitude oscillations at finite Reynolds number [PDF]
, 1993 The unsteady force acting on a sphere that is held fixed in a steady uniform flow with small-amplitude oscillations is evaluated to O(Re) for small Reynolds number Re. Good agreement is shown with the numerical results of Mei, Lawrence & Adrian (1991) up
