Abstract

Abstract : An experimental study of the turbelent mixing of subsonic axisymmetric gas streams was conducted. Hydrogen-air and air-air mixing systems were studied, and the velocity ratio (jet velocity/outer stream velocity) was varied from 2.4 to 6.3. Special emphasis is placed on (1) the centerline decay and radial profile shapes of composition, velocity, and total enthalpy and (2) the relationships between the turbulent transport of mass, momentum, and energy. The major conclusions drawn for this particular set of conditions are (1) for the hydrogen-air system the centerline decay decreases with increasing velocity ratio, (2) profile similarity of composition, velocity, and total enthalpy is a valid assumption, (3) there is a definite relationship between the transport of momentum and energy which is not compatible with a constant Prandtl number, and (4) unity Lewis number is a valid assumption. The experimental data obtained are tabulated for the benefit of other investigators.
