CARBON-DIOXIDE ABSORPTION INTO A STABLE LIQUID RIVULET

The wetting of the flow surfaces in heat exchangers, trickle-bed react ors and columns containing structured packing has been shown to be dis crete in nature involving rivulets. Detailed, fundamental modelling of the flow structure and transport processes occurring in rivulet flow is required in order to provide a basis from which more complex models can be built describing the overall processes occurring in the partic ular application of interest. To demonstrate the applicability of deta iled rivulet modelling, theoretical analysis of the velocity and mass transfer characteristics in rivulet flows in an inclined, flat plate a bsorber has been performed. These theoretical results are compared wit h experimental data.
