- S053022 Visualization of Structures of Vortex Array in Circular Synthetic Jets
抄録
Structures of vortex rings in circular synthetic jets are studied by smoke visualization. The smoke particles engulfed by the vortex rings are illuminated by thin sheet of laser light and the motion the mushroom shaped smoke patterns by vortex rings are recorded by a high-speed digital camera. The experiments are carried out for 5 driving conditions of dimensionless stroke L/d range from 0.725 to 4.74 at Reynolds number Re ≈ 2500 and 6660. The visualized images show that the vortex rings rolled up from the orifice form an array of vortex rings and travel to downstream. In some distance from the orifice, the vortex rings are collapsed. During the collapse of the vortex ring, no direct interferences with other vortex rings are observed. The visualized cross sections normal to jet axis indicate that there exist small and irregular pattern inside the vortex rings.
