✦ Synopsis

A new turbulent intermittency detector method, based on the Turbulent Energy Recognition Algorithm (TERA), has been proposed. Its performance was compared with two other available methods using the data obtained from hot-wire measurements in a developing boundary layer flow on a concave surface with constant radius of curvature of 2 m. Comparisons show that this new method is better than the other two as a turbulent detector under the same flow conditions, especially in the near-wall and in the outer and outside regions of the boundary layer.

The development of the transitional boundary layers on a flat plate in uniform and non-uniform incoming flows was experimentally investigated. The mean velocity profiles and the wall shear stresses on a flat plate were measured in the wakes which were generated by circular cylinders and a flat plate
