خلاصه مقاله:
The hydrodynamic of internal reactors with a riser diameter of 4cm and 5cm operating with air and water system have been experimentally investigated for a range of superficial gas velocity. Herewe have used 2 internal loops with 4cm and 5cm internal diameter. For each velocity we havemeasured the gas hold up. The gas phased sparged in to the column by means of 4 different spargers with different number of holes in 1mm diameter. The results show that the gas distributerplays an important role on the evolution of the bubble size distribution in gas-liquid reactor. Soone of the main subjects of the present work is to study the influence of sparger design
