dc.description.abstract | In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was examined. Also, the possibility of theoretical prediction of this liquid circulation velocity was assessed. The correlation originally proposed by Glennon et al. (Chem. Eng. Commun. 121 (1993) 183-192) for two phase system liquid velocity prediction was extended and corrected for application to three phase systems. The accuracy of this new correlation was tested on our experimental data. The corrected correlation shows higher accuracy than the originally proposed one. In addition, the influence of reactor geometry and solid loading on reactor working performances was established. | en |
dc.description.abstract | U radu je ispitivan uticaj visine i prečnika pneumatskih reaktora sa spoljašnjom cirkulacijom kao i udela čvrste faze na brzinu cirkulacije tečnosti i druge hidrodinamičke osobine reaktora. Takođe, u radu je analizirana i mogućnost teorijskog predviđanja brzine cirkulacije tečnosti. Jednačina predložena od strane Glenona (B. Glennon) i saradnika (Chem. Eng. Commun. 121 (1993) 183-192) za određivanje brzine tečnosti u dvofaznim sistemima, proširena je i korigovana, i na taj način je omogućena njena primena na trofazne sisteme. Tačnost nove jednačine je ispitana na našim eksperimentalnim podacima. Korigovani oblik jednačine daje rezultate bliže eksperimentalnim vrednostima od originalne jednačine. | sr |
