Hot-wire measurements were carried out in a fully developed turbulent pipe flow disturbed by rough wall sections (containing d- and k-type roughness) with emphasis being placed on the dependence of the statistical turbulence properties on the type of roughness. A sufficient length of pipe was provided downstream of the disturbance to ensure recovery to the equilibrium state.
