Effects of curvature and pressure gradient on a turbulent near wake

摘要

In an earlier study experimental data were presented for the turbulent near wake of a flat plate subjected to an adverse pressure gradient. This paper presents new data on the simultaneous effects of curvature and adverse pressure gradient. The results are compared with new data for the wake under zero pressure gradient. The measurements were performed with a three-component laser-Doppler velocimeter, and include mean velocities and Reynolds stresses. Temporal correlation functions of the streamwise velocity component were measured to determine the dissipation length scales. These data can be used as a testcase for turbulence models.
