Measurements of the velocity distribution in a plane turbulent jet of air

The present paper deals with the velocity distribution across a plane jet of air issuing with a discharge velocity of 4000 cm s−1 from a slit of 0.5 cm × 10 cm into still air, and across a plane jet of air issuing with a discharge velocity of 2000cms−1 from a slit of 1 cm × 25 cm into still air. In both cases the Reynolds number amounted to 13 300. After a survey of the relevant theories, experiments of other investigators are reviewed. The paper then describes the experimental equipment and the experiments performed. From these experiments three characteristic quantities have been derived: the turbulent shear stress, the coefficient of turbulent momentum exchange, and the mixing length.
