Studies on the mixing of two non-axial plane jets in a confined passage: mean flow characteristics

The present study deals with the static pressure and mean velocity fields generated due to the mixing of two plane turbulent jets in a confined passage. Four different impingement angles, viz., 15, 30, 45 and 60 degrees, have been investigated. It is found that the inlet angle is the most important parameter governing the extent of the central recirculation zone, the wall recirculation zones, the position of the confluence point and the distance required for complete mixing. The rate of decay of the maximum velocity is very rapid for inlet angles exceeding 45 degrees. © 1991 Springer-Verlag.
