Web23 de ago. de 2003 · 4 Flow structure. The dynamics of swirling jet flows are examined for three different configurations: the outer flow rotating only case (OFRO), the inner-jet rotating only case (IJRO) and the reference case. For all four configurations, the Reynolds number and the velocity ratio are maintained equal to Re =2000 and ζ =2.5. WebHierarchical Vortex Regions in Swirling Flow.
