DEVICE AND METHOD FOR INFLUENCE AT VORTICAL STRUCTURES IN TURBULENT AIR JET |
摘要 |
FIELD: machine building. ^ SUBSTANCE: invention is related to devices for influence at flow of fluid medium. Device for influence at vortical structures in turbulent air jet flowing from air exhaust channel comprises pair of needles installed in close proximity to flow and connected to source of AC voltage for creation of pulsating corona discharge between needles. One needle from pair of needles is oriented in direction along flow, and the other needle - across flow. Method is characterised with influence of pulsating corona discharge at vortical structures in turbulent air jet. ^ EFFECT: reduction of jet noise. ^ 12 cl, 4 dwg |
