Orbiting Cylinder at Low Reynolds Numbers

Part of the IUTAM Bookseries book series (IUTAMBOOK, volume 14)

Abstract

Sudden changes found in the time-mean and rms values of force coefficients of a circular cylinder in forced orbital motion placed in a uniform stream when plotted against ellipticity of the orbital path suggest that two solutions (states) exist. For a better understanding of the changes in state, some new factors are considered: the torque coefficient; computations for Reynolds numbers up to 300; the investigation of lock-in domain for Re = 160.
