Interfacial area for concurrent gas-liquid upflow through packed bed
Interfacial area is measured for a large range of column packing (Raschig rings, Intalox saddles, and two sizes of spheres) for concurrent gas–liquid upflow through packed bed covering bubble, pulse and early spray flow regimes using air–aqueous sodium sulfite solution. It was observed that the inte...

description | Interfacial area is measured for a large range of column packing (Raschig rings, Intalox saddles, and two sizes of spheres) for concurrent gas–liquid upflow through packed bed covering bubble, pulse and early spray flow regimes using air–aqueous sodium sulfite solution. It was observed that the interfacial area increased with increase in fluids flow rate and decreased with the increase in the particle size for the same type of packing. A correlation (3 ≤ Rel ≤ 165, 0.5 ≤ Reg ≤ 210) was developed using present data (120 data points) and literature data (100 data points), which predict the interfacial area with an rms deviation of 16%.
La zone interfaciale est mesurée pour une vaste gamme de remplissage (anneaux de Raschig, selles Intalox et deux tailles de sphères) pour un courant ascendant gaz‐liquide simultané dans un lit fixe couvrant les régimes de bulles, d'impulsions et de flux de pulvérisation précoces au moyen d'une solution de sulfite de sodium atmosphérique‐aqueuse. On a observé que la zone interfaciale s'accroissait avec l'augmentation du débit des fluides et diminuait avec l'augmentation de la taille des particules pour le même type de remplissage. Une corrélation (3 ≤ Rel ≤ 165, 0.5 ≤ Reg ≤ 210) a été créée au moyen des données actuelles (120 points de données) et des données de la littérature (100 points de données) qui prédisent la zone interfaciale présentant un écart‐type de 16%. |
