Featured researches published by Dragan Lj. Petrović.


Chemical Engineering Science | 1993

Minimum fluidization velocity of large particles in a draft tube airlift reactor

Dragan Lj. Petrović; Duško Pošarac; Aleksandar P. Dudukovic; Dejan Skala

The effects of solids loading and diameter, liquid properties and draft tube to outer column diameter ratio (D D /D) on minimum fluidization velocity in a draft tube airlift reactor (DT-ALR) are presented


Chemical Engineering Science | 1990

Mixing time in gas—liquid—solid draft tube airlift reactors

Dragan Lj. Petrović; Duško Pošarac; Aleksandar P. Dudukovic; Dejan Skala

The results of an experimental investigation of the mixing time in three-phase draft tube airlift reactors are presented. The influences of the gas superficial velocity, draft tube to outer column diameter ratio, concentration and diameter of solid particles on mixing time and circulation time were studied


Industrial & Engineering Chemistry Research | 2003

Solids holdup and pressure drop in gas-flowing solids-fixed bed contactors

Aleksandar P. Dudukovic; Nikola M. Nikačević; Dragan Lj. Petrović; Zlatica J. Predojević
