Abstract
For an axisymmetric turbulent jet diffusion field with scalar(heat) transfer, the experimental investigations of passive and active controls are performed with vortex generators that have angle of attack of 30° with respect to the flow. Passive controls with 1, 2, and 6 vortex generators being projected and active controls with vortex generatos being projected in phase, in turn, and in alternate shifts are conducted. Effects of vortex generatos and their motion on turbulent jet are examined.
