Abstract An experimental investigation of the statistical properties of the velocity difference in an anisotropic turbulent cylinder wake at moderate Re λ is conducted by a triple hot-wire anemometer (HWA) probe. The energy spectra show a clear large scale anisotropy due to the presence of the Von Karman vortices. In spite of the low Re λ and the large scale anisotropy, the extended-self-similarity (ESS) allows location of broad scaling ranges and the calculation of the scaling exponents of the three velocity structure function components in order to examine the intermittency anomalies. More intermittent behavior of the transverse velocity components with respect to the longitudinal one is found both by ESS and by comparison of the longitudinal and transverse velocity difference probability distribution functions (PDF).
