Abstract
In this numerical study a circular cylinder is made to follow a figure-8 path. Time-mean and rms values of force coefficients and mechanical energy transfer are investigated versus frequency ratio at Reynolds numbers of 200, 250 and 300. Results differ substantially depending on the direction of orientation. Mechanical energy transfer was found to be always positive when the upper section of the figure-8 path moved in an anticlockwise direction, which may lead to vortex-induced vibration, and always negative for a clockwise path.
