Sammanfattning

The present paper proposes an application for an Euler-Lagrangian one-way coupling method in CO2 bubble tower design. A simplified flow field is presented as the basis of this research work for a slice of fluid and a rotating mesh model is presented as the base of the simulation, in this case involving a mixing rotor. A Turbulent Flow interface from Comsol is used. CO2  concentration as function of time and position is studied. Bubble motion is tracked separately in a Lagrangian spherical particle, in this case using the Comsol Particle Tracing module. A link between mass transfer boundary layer and bubble force is established through the mass time derivative of the dissolving bubble, included as the mass change rate of the particle as function of the local Reynolds, Schmidt and Sherwood number of a spherical bubble using mass diffusion theory.
