An Experiment on the Wake of a Slender Propeller-Driven Body

Abstract

The momentumless wake of a slender propeller-driven model in a wind tunnel at a Reynolds number of 63000 (based upon diameter) is examined using the hot-wire anemometer. Measurements of the mean flow field including swirl are presented, as well as measurements of the turbulent intensity and Reynolds stress within the first 20 diameters behind the model. The data are compared with a previous experiment at a similar Reynolds number using a blunt body and a high-speed jet as the propulsion source. A theoretical model of the flow is presented which describes the flow quite well, at one location.
