Abstract EN
Traveling wave analysis of a recently developed two-fluid model for bubbly flow in lab-size packed beds is used to propose a constitutive closure for the effective viscosity, a nonzero parameter that is needed in the liquid momentum balance to avoid the prediction of disturbances with an infinite growth rate.
Near-solitary wave profiles are predicted over a range of velocity parameters consistent with linear stability analysis.
Centimeter-scale periodic disturbances are predicted in the near-pulsing regime.
Preliminary estimates of average pulse properties compare well with typically reported experimental values.
Initial comparison with time integration subject to periodic boundary conditions shows agreement of the liquid saturation profiles but differences in the liquid velocity profiles.
