Descriptions
Measurements of higher order products, that is multiple correlation, were made in the fully developed two-dimensional wake produced by a circular cylinder. It was found that the profile of the triple and fourth order moments of fluctuating velocity components were attained in the self-preservation beyond x/d=211.0. The skewness and flatness factors across the section were also presented. The turbulent kinetic energy budget for the present measurement doesn't correspond so well with Townsend's work.
