Abstract
U ovom radu određivana je brzina neometanog taloženja sferičnih čestica različitih veličina, ali i onih nepravilnog oblika, tzv. nesferičnih čestica. Brzine taloženja određivane su eksperimentalno u koloni za određivanje brzine taloženja vlastite izvedbe, kao i korištenjem teorijskih izraza, odnosno primjenom C D – Re dijagrama. Dobiveni rezultati ukazuju da povećanje veličine sferičnih i nesferičnih čestica, kao i povećanje razlike gustoća između čestica i fluida, značajno utječe na brzinu neometanog taloženja. Analizirano taloženje odvijalo se u prijelaznom hidrodinamičkom području optjecanja, zbog čega nije bio primjenjiv Stokesov zakon za određivanje brzina taloženja. Stoga se kao neminovnost nametnula uporaba C D – Re dijagrama. Podaci o brzinama taloženja i veličini čestica dobiveni primjenom C D – Re dijagrama pokazuju vrlo dobro slaganje s eksperimentalno dobivenim rezultatima.
Abstract (english)
In this bachelor thesis, the unhindered settling velocity for spherical particles of different sizes, as well as for those of irregular shapes, the so-called non-spherical particles, was determined. The settling velocities were determined experimentally in the column for determining the settling velocity of our own performance, as well as using theoretical expressions, i.e. using C D - Re diagram. The obtained results indicate that the increase in the size of spherical and non-spherical particles, as well as the increase in the density difference between particles and fluid, significantly affects unhindered settling velocity. The analyzed settling took place in the transient hydrodynamic area of circulation, which is why Stokes' law was not aplicable for settling velocity determination. Therefore, the use of C D - Re diagram was inevitable. Data on the settling velocities and particles size obtained using C D - Re diagram show very good agreement with the experimentally obtained results.
