In this paper the k−11 spectral law is examined using the experimental data from fully developed pipe, boundary layer, and diffuser flows (here, k1 denotes a one-dimensional longitudinal wavenumber). The type of pressure gradient present in a wall-bounded flow has been found to play a controlling role on the presence and extent of the k−11 spectral law. In fully developed pipe and boundary layer flows, under favorable and zero pressure gradients, respectively, the occurrence of the k−11 spectral law shows similar characteristics. On the other hand, the presence of adverse pressure gradient has been observed to modify these characteristics.
