An Experimental Study of the Turbulent Mixing of Subsonic Axisymmetric Gas Streams

OBJECTIVE: The objective of this experimental investigation was to document the turbulent mixing of subsonic axisymmetric hydrogen and air streams at velocity ratios which have not been previously reported. Special emphasis is placed on [1] determining the effect of velocity ratio and density gradients on the centerline decay of composition, velocity, and total enthalpy, and on the composition, velocity, and total enthalpy profile shapes, and [2] presenting nondimensional composition, velocity, and total enthalpy relationships which are indicative of the turbulent Prandtl, Lewis, and Schmidt numbers.
