dc.description.abstractWe analyse the forces on a 45∘ inclined 6:1 prolate spheroid at Reynolds number ReD = 8000. In contrast to flow at lower Reynolds numbers previously investigated, we now find a strong oscillatory behaviour in the global forces. The Strouhal number associated with the forces is 0.05 and the peak-to-peak value of the oscillations in the sideforce is more than 25% of the average. A Fourier transformation of the entire flow field reveals that the cause of the force fluctuations is spatial oscillations in one of the two primary vortices generated behind the spheroid. This phenomena is attributed to a three-dimensional vortex instability.nb_NO
