Studies on the mixing of two non-axial jets in a confined passage — turbulence characteristics

The mean characteristics of the flow due to mixing of two non-axial plane jets in a confined passage, were reported previously by Manjunath et al. (Exp. Fluids 11 (1991), 17–24), as part I. In this paper, the turbulence characteristics of the flow are discussed. The various components of the Reynolds stress tensor are reported for the four inlet angles considered, viz., 15°, 30°, 45° and 60°. As expected from the mean flow field, the inlet angle influences the distribution of the various turbulence components through the relative size of the recirculation zones and the turbulence field is different for the smaller angles of 15° and 30° in comparison to those for 45° and 60°.
