The flow around a twisted cylinder at a subcritical Reynolds number (Re) of 3000 is investigated using large eddy simulation (LES). The instantaneous wake structures of the twisted cylinder is compared with those of a circular and a wavy cylinder at the same Re. The shear layer of the twisted cylinder covering the recirculation region is more elongated than those of the circular and the wavy cylinder. Successively, vortex shedding of the twisted cylinder is considerably suppressed, compared with those of the circular and the wavy cylinder. Consequently, the mean drag coefficient and the fluctuating lift of the twisted cylinder are less than those of the circular and the wavy cylinder.
