Abstract
Results of an experimental investigation of the inhomogeneous, three-dimensional flow around a surface mounted cube in a channel are presented. LDA measurements of single-point velocity correlations are used to determine the production, convection and transport of the turbulence kinetic energy, k, in the obstacle wake. The turbulence dissipation rate is obtained as a closing term to the balance of the k-transport equation. The results provide some insight to the evolution of the turbulence dissipation rate from the near field recirculation zone to the asymptotic wake. Also presented is a comparison between measured and modeled transport terms.
