Download or read book Fine Scale Structure of Turbulent Velocity Fields written by Frank H. Champagne and published by . This book was released on 1976 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of three turbulent shear flows-a two-dimensional mixing layer, a high Reynolds number axisymmetric jet, and a cylinder wake-was completed. The measurements provide new information on the higher-order statistical characteristics of these flow fields and on the development of the mixing layer flow towards a self-preserving state. The relevance of initial conditions on the development of the mixing layer flow is considered in light of both present and previous data. An investigation of the validity of the Kolmogorov local similarity theories for the fine scale structure of turbulent velocity fields was undertaken. The importance of considering effects on spectra caused by deviations from Taylor's hypothesis in high intensity flows was demonstrated. Finally an experimental study of the relaminarization of turbulent pipe flow subjected to a large decrease in Reynolds number was initiated.
