    In this study, numerical simulations of binary droplet collisions of two GNF droplets are carried out. Navier-Stokes equations are solved for fluid motion both inside and outside of the droplet using a conservative ...
  • Numerical approach to study bubbles and drops evolving through complex geometries by using a level set – Moving mesh – Immersed boundary method 

    Gutiérrez González, Ernesto; Favre, F.; Balcázar Arciniega, Néstor; Amani, Ahmad; Rigola Serrano, Joaquim (2018-10-01)
    Article

    Master thesis
    Open Access
    This thesis represents a numerical method to solve fluid-structure interaction (FSI) prob- lems where the fluid exhibits a non-Newtonian behavior. Oldroyd-B constitutive equa- tions is used to model Viscoelastic fluid and ...
  • Numerical study of binary droplets collision in the main collision regimes
