The flow field past a cylindrical model with a cactus-shaped cross section is investigated in a wind tunnel. The velocity field in the immediate wake just aft of the cylinder and the surface pressure distribution are measured. The data from the cactus model are compared to a similar model with a circular section. The mean flow patterns have generally a similar form for the two geometries. However, there are differences in the surface pressure distribution and the turbulent velocity levels in the wake.
