Developing turbulent flow in concentric annuli: An analytical and experimental study

Abstract

Abstract. In this paper, the problem of the developing turbulent flow in concentric annuli is studied from an integral view-point based on a modified model of REICHARDT'S expression for the eddy diffusivity of momentum. The analytical results are compared with the experimental data based on the measurement of local flow conditions for air flow through four concentric annuli for a Reynolds number range of about 20
