Ključne riječi:

simultani prenos količine kretanja, toplote, mase, jedna kapljica

Sažetak

Kombinovani prenos količine kretanja, toplote i mase na kapljici javlja se u velikom broju tehničkih procesa kao što su: sušenje mlaza, hlaĎenje mlaza, kristalizacija mlaza, ciklonsko isparavanje, sagorevanje tečnog goriva, mlaz ili prostor ispune rashladnog tornja i vodeni mlaz ispod ispune rashladnog tornja, komora za kondicioniranje vazduha, direktnim kontaktnim kondenzatorima u termoelektranama.

Uprkos činjenici da su se ove operacije koristile pre 5000 godina (evaporativno hlaĎenje) i relativno mlaĎi proces kao što je sagorevanje tečnog goriva koje je staro 120 godina, provoĎena su intenzivna istraţivanja u zadnjih nekoliko decenija na ovom polju. Čak i jednostavni problem jedne kapljice uključuje ova tri transportna fenomena i daleko je od razrešenja i detaljnog razumevanja za kompletnu oblast varijabli od praktičnog interesa.
