WebFlooding in countercurrent flow of air and water in inclined tubes has been investigated. Data on flooding inception in the whole range of inclinations have been collected and predictive models for calculating the flooding conditions as a function of the flow rates and pipe inclination were proposed. http://www.columbia.edu/itc/seas/E3810-lab/pbd.html WebJul 11, 2015 · At incipient flooding there is high interfacial activity due to momentum transfer between gas and liquid. The intensity of interfacial activity may be further increased and hence the mass transfer coefficient, by increasing packing density. However there is a maximum packing density above which fluidised operation is impossible. irb in research meaning
