The anisotropy of the dissipation rate tensor has been studied in the self-preserving region of a cylinder wake. Hot-wire techniques have been employed to measure velocity derivatives in the stream-wise, lateral and normal direction. From these measurements the stream-wise diagonal component of the dissipation rate tensor was determined and compared to that predicted by an anisotropic dissipation model. It was found that the dissipation rate anisotropy could essentially be accounted for by the employed model. Triple velocity correlations were also measured and compared with corresponding profiles obtained from closure models.
