Hierarchical vortex regions in swirling flow
Web16 de ago. de 2024 · A cost-effective technique to dissipate the energy in hydropower systems is the formation of a swirling flow within a tunnel. In such flows, an air core with a significant cross section usually occurs. To reveal the air-core features in the horizontal tunnel of a high-head shaft spillway, laboratory tests, numerical modeling, and prototype … 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.
