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 U _jd/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 R _λ and the local Reynolds number R _c (based on local velocity and length scales) are found to be related as Rλ ∼ 2.3R _c ^1/2.
