This kind of flow has set of technical<br>applications related to fuel combustion; therefore, various approaches to intensifying gas mixing in<br>this type of flow are proposed and studied. This work is devoted to the approach which implies using<br>electric discharges for pulsed heating of the medium and generating the instabilities in the shear layer<br>at the boundary of the secondary jet. In the software package FlowVision the characteristics of the<br>flow are simulated in the absence and presence of pulsed-periodic local heating on the injector<br>windward side. The calculations are performed for three jet-to-crossflow momentum flux ratios: 0.7,<br>1.0 and 1.3. Six modes of pulse heating are investigated: they have different frequencies of pulsed<br>heating (from 10 to 60 kHz), but they have the uniform average power release. This work<br>demonstrates that pulsed heating can stimulate the formation of perturbations in the shear layer at<br>the jet boundary and can lead both to a decrease in the average mixing efficiency and to its increase<br>(up to 15%). The optimal frequencies of the pulsed heating are found.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/06\/HiSST-2024-194.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Aleksandr A.
