Study of Unsteady Fluid Forces on a Rotationally Oscillating Circular Cylinder
Journal of the Visualization Society of Japan, 2005 The characteristics of fluid forces on a rotationally oscillating circular cylinder in a uniform flow are studied experimentally at various forcing frequencies and rotational amplitudes of cylinder oscillation. The measurements are made on the pressure fields around the circular cylinder by using the velocity data measured by PIV in conjunction with ...

The leading effect of fluid inertia on the motion of rigid bodies at low Reynolds number [PDF]
, 2004 We investigate the influence of fluid inertia on the motion of a finite assemblage of solid spherical particles in slowly changing uniform flow at small Reynolds number, Re, and moderate Strouhal number, Sl. We show that the first effect of fluid inertia

Unsteady Fluid Force Acting on Two-Dimensional Circular Cylinder Bundles on Fluid-Elastic Vibration.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1998 In this paper we describe the flow around two-dimensional circular cylinder bundles supported by wires. The experiment was carried out in an N.P.L. blow-down-type wind-tunnel with a working section of 500mm×500mm×2000mm, and with the Reynolds number of 9.4×103.
