Effects of curvature and pressure gradient on a turbulent near wake

In an earlier study (Tummers [1]) experimental data were presented for the turbulent near wake of a flat plate subjected to an adverse pressure gradie nt. This paper presents new data on the simultaneous effects of curvature a nd adverse pressure gradient. The results are compared with new data for th e 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 veloci ty component were measured to determine the dissipation length scales. Thes e data can be used as a testcase for turbulence models.
