Pressure loss and liquid holdup in packed bed reactor with cocurrent gas-liquid down flow
TL;DR: In this paper, a two-phase pressure loss based on an energy (not momentum) balance was correlated in terms of Lockhart-Martinelli parameters as follows : φl=1.30+1.40 as 1/3χ0.22 (as in mm-1)
Journal ArticleDOI
Liquid-to-particle mass transfer in fixed bed reactor with cocurrent gas-liquid downflow
TL;DR: In this paper, the mass transfer coefficient kls was measured over a range of flow rates of gas Ug = 0-100 cm and liquid Ul = 0.05-25 cm in a column packed with spheres of three different diameters.
Journal ArticleDOI
Liqusd phase mass transfer in packed bed reactor with cocurrent gas-liquid downflow
TL;DR: In this article, a column packed with glass spheres of 3 different sizes (2.59-12.2 mm) was measured for two-phase cocurrent flow of O2-water and CO2-NaOH systems.

TL;DR: In this article, a simple model of discharge flow is proposed and related with the results obtained by measurement of average circulation velocity, which is proportional to impeller speed and the sine of the impeller blade angle.
