Equilibrium parameters for twodimensional turbulent wakes
Abstract
The parameters characterizing a plane turbulent wake in its equilibrium state of development are determined on the basis of experiment and analysis. Measurements are made in an opencircuit suctiontype wind tunnel with a contraction ratio of about 10 and a testsection of about 30 cm sq and 4.27 m long. Less than 1.5% variation in wind speed along the test section is attained by applying suitable divergence for the boundary layer growth. A twodimensional wake is created behind a twin plate configuration at a freestream velocity of 21.3 m/s. The freestream turbulence level at this speed is about 0.15%.
