Hot wire measurements in the far field region of the plane wake of a cylinder have been carried out. The data obtained indicated that transverse distributions of mean-velocity and Reynolds stresses were self-preserving for a downstream distance greater than 400 momentum thicknesses. Dissipation rate and triple velocity correlations were measured at a downstream position of 880 momentum thicknesses, these measured profiles were compared with the profiles obtained from closure models for the Reynolds stress equations. It was found that the dissipation rate anisotropy could essentially be accounted for by the employed model, larger deviations were observed between the measured and modelled profiles for the triple velocity correlations.
