Slip Velocity and Gas Holdup in a Gas-Liquid Co-current Upflow through a Packed Bed

Abstract

Experiments were carried out in a co-current two phase upflow through a packed bed reactor using four different liquid systems and five different particles with air as the dispersed phase. An attempt has been made to predict the gas phase holdup using a slip velocity approach. The dependency of the slip velocity on the fundamental variables involved in the system are discussed in detail. Generalized correlations are proposed based on 1650 data (both 1253 experimental and 397 literature data) to represent the slip velocity and gas phase holdup in terms of basic dimensionless groups.
