Numerical And Experimental InvestigationOf Oscillating Flow Around A Circular Cylinder

The objective of this paper is the numerical and experimental investigation of oscillating flow around a circular cylinder. The finite element method was used for the solution, whereas the experiments were conducted in a U-shaped tube. The computation and experiment were performed at Keulegan-Carpenter numbers extending up to 10 and frequency parameters equal to 34 and 53. From the traces of the in-line force exerted on the cylinder the force coefficients were evaluated. Good agreement was found between computational results and experimental measurements.
