Abstract:

The in-line and transverse forces acting on cylinders and the in-line force acting on spheres placed in a sinusoidally oscillating fluid have been measured. The periodic flow was generated in a U-shaped vertical water channel through the use of a pneumatic oscillator. The drag, inertia and the lift coefficients as well as the total force coefficient have been determined through the use of Fourier analysis and found to depend on a period parameter.
