Abstract

The mean rate of dissipation ∈ is measured along the axes of a plane jet and three circular jets, covering good ranges of the jet Reynolds number Ujd/v and the downstream distance x. The data confirm the universal relations, derived from requirements of self-preservation, between ∈ and x, for both the circular jet and the plane jet. For either type of jet, the turbulence Reynolds number Rλ and the local Reynolds number Rc (based on local velocity and length scales) are found to be related as Rλ ∼ 2.3Rc1/2.
