“…Furthermore, the core of the chamber happens to be the region of highest axial velocity; thus, the particles that are tagged in the first exposure may have traveled below the laser sheet by the time the second image is taken. This scenario can also lead to decreased confidence in the correlated data in the core region (see also Hu et al, 2005).…”

“…Gaunama algebrinių lygčių aibė, kurią galima išspręsti taikant iteracinius metodus ir gauti kintamųjų -greičio komponentės ir slėgio -pasiskirstymą lauke, priklausantį nuo ribinių sąlygų, apibūdinančių konkretų uždavinį (Bernardo et al 2006). Dėl labai sudėtingų trijų dimensijų sūkurinių srautų ciklono viduje supratimas apie ciklone vykstantį kietųjų dalelių atskyrimo iš dujų srauto procesą tebėra nepakankamas, nepaisant to, kad dujų ir kietųjų dalelių suspensijos srauto judėjimas ciklonuose jau seniai yra daugelio eksperimentinių, teorinių ir skaitinių tyrimų objektas (Zhoue, Soo 1990;Hu et al 2005;Gujun et al 2008). Norint ištirti srauto struktūrą eksperimentiniuose ciklonuose dažnai taikomi įvairūs matavimo metodai, tačiau šių metodų trūkumai trukdo susidaryti išsamų vaizdą apie srauto sudėtingumą (Nieuwland et al 1996;Gujun et al 2008).…”

“…It may thus be speculated that data obtained from a more focused experiment could be higher and less noisy than the ones considered here. Interestingly, the reduced fidelity in the vicinity of the core is also depicted in the Reynolds shear-stress model data and laser doppler velocimetry (LDV) measurements taken by Hu et al (2005). Their LDV data acquisition system also deteriorates inwardly, past the point of maximum swirl.…”

“…When the flow field is surrounded by solid boundaries, the effects of no slip at the walls and singularities at the core can significantly alter the bulk motion. In practice, the characteristics of the core are relatively well understood and have been described by Ogawa (1984), Vatistas et al (1986), Hoekstra et al (1998) and more recently by Derksen & Van den Akker (2000), Fang et al (2003), Rom et al (2004), Murray et al (2004) and Hu et al (2005). Nonetheless, a rigorous analytical model for the core is still lacking, especially at high Reynolds numbers.…”
