Shear Deformation of Droplets Using DPD

A droplet (liquid–liquid phase separation) model was created using Dissipative Particle Dynamics (DPD), and after placing surfactants at the interface, shear flow was applied to analyze droplet deformation behavior. It was confirmed that deformation increased with shear rate γ and that deformation was affected by the presence of surfactants.
Use Cases Highlights
  • Analysis of droplet deformation using DPD
  • Consideration of changes in interfacial tension due to surfactants
  • Evaluation of the effect of shear rate on degree of deformation

Droplet deformation behavior

Results of droplet deformation under different shear rates γ are shown. Presence or absence of surfactant affects interfacial tension and thus deformation.
