Abstract:

Turbulent coaxial air-air mixing and hydorgen-air mixing were studied. The ratio of outer stream to jet velocity was varied from 0.12 to 1.52 for the air-air mixing streams and from 0.16 to 0.42 for the hydrogen-air systems. Special emphasis was placed on the determination of the turbulent transport properties especially the eddy viscosity and the Prandtl number from the mean flow field measurements by use of an integral technique. Radial and axial profiles of velocity, concentration, shear stress, and eddy viscosity are presented, as well as radial profiles of the turbulent Prandtl number and representative static pressure profiles.
