Abstract

The object of this experiment is to make a study of a fully developed turbulent flow at a very high Reynolds Number, using a large circular tube, through with air was drawn. In determining the behavior of the air stream, Pitot tubes were used in the present experiment. This investigation is a preliminary study of the turbulence and other characteristics of the tunnel for the subsequent experiment to be conducted by Mr. A. M. Kuethe of the California Institute of Technology. In the subsequent experiment, a direct measurement of the eddying motion and a determination of the values of mischungsweg distribution of the turbulent flow will be made at the same measuring sections in the same tunnel, using an electric anemometer and oscillograph method.
