CHARACTERISTICS OF AXISYMMETRIC AND TWODIMENSIONAL ISOENERGETIC JET MIXING ZONES,
Abstract
The characteristics of an axisymmetric mixing zone are derived and numerically evaluated for turbulent isoenergetic mixing. Tables of mass flow and momentum integrals are presented for twenty-eight Crocco numbers in the range 0 to 1.0. This is an expansion of the work done by Korst, which covers the Crocco number range from 0 to 0.916. It is theoretically shown that an axisymmetric mixing zone can be treated as a two-dimensional mixing zone if the projected thickness of the mixing zone on the radius of symmetry is less than 0.30 of the radius of symmetry. Applying the results of this analysis to Korst's supersonic base pressure theory shows that axisymmetric effects on mixing tend to increase base pressure relative to the two-dimensional value.
