The Effect of Density Differences on the Turbulent Mixing Layer,
Abstract
An experimental study has been made of the turbulent mixing layer between two streams of different gases, especially nitrogen and helium. This was made in a new flow apparatus, designed to produce good quality flow at pressures up to 10 atmospheres with run times as low as 1 or 2 seconds. High-speed measurement techniques, including a novel density probe, were used. The similarity properties of the mixing layers are established from profiles of mean velocity and density, and from these the basic flow parameters are computed including spreading rate, dissipation rate, and shear stress distribution.
