Application of the Von Karman Momentum Theorem to Turbulent Boundary Layers

Abstract

A study is made of the Von Karman momentum theorem with respect to its application to turbulent boundary layers in a positive pressure gradient. Although the Von Karman momentum theorem for turbulent boundary layers contains momentum terms due to the fluctuating motion as well as momentum terms due to the mean motion, the general practice has been to neglect the momentum terms due to the fluctuating motion. Data were obtained from Schubauer and Klebanoff (NACA TN 2133) and Ludwieg and Tillmann (NACA TM l285) with which both the terms due to the mean flow and the terms due to the fluctuating flow could be evaluated.
