Drop Breakup in an SMX Static Mixer in Laminar Flow
Authors:Shiping Liu  Andrew N Hrymak  Philip E Wood
Abstract:The mechanism of drop breakup inside SMX static mixers in the laminar flow regime was studied using experimental observations and computational fluid dynamics (CFD). The deformation and breakup of a single drop was simulated using the volume of fluid (VOF) model. It was observed that drops break up after collision with the leading edges and cross‐points of the bars in the SMX static mixer. It was found that drop collision with the bar cross‐points of the SMX static mixer elements is most effective for drop breakup. Elongation and folding result in drop breakup at the cross‐points.
Keywords:drop breakup  SMX static mixer  laminar flow  VOF  CFD
