MIXING IN A SYSTEM OF PLANE COCURRENT JETS OF AN INCOMPRESSIBLE LIQUID OVER THE MAIN PORTION A. I. Kuz'min and S. S. Kharchenko UDC 532.517.4 We consider mixing in a periodic system of plane subsonic jets of an incompressible liquid for laminar and turbulent flows. Asymptotic expressions for the change in the velocity defect are obtained. A comparison with a numerical calculation and with existing experimental data is carried out. We show that under the conditions considered the accuracy of the expressions derived is rather high and they can be used for evaluating the mixing velocity over the main portion of mixing.
