This paper represents a numerical method to solve fluid-structure interaction (FSI) problems where the fluid exhibits a non-Newtonian Viscoelastic behaviour. Oldroyd-B constitutive equation is used to model Viscoelastic fluid. ...

A finite-volume based conservative level-set method is presented to numerically solve the non-Newtonian multiphase flow problems. One set of governing equations is written for the whole domain, and different phases are ...

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 ...

The dynamics of binary droplets collision is of huge importance in different fields, from multiphase reactors (Dudukovic et al in Chem Eng Sci 54:1975–1995, 1999 [11]), raindrop formation, ink-jet printing, spray combustion, ...

The present work proposes a method to study problems of drops and bubbles evolving in complex geometries. First, a conservative level set (CLS) method is enforced to handle the multiphase domain while keeping the mass ...

The complex nature of multiphase flows, particularly in the presence of non-Newtonian rheologies in the phases, limits the applicability of theoretical analysis of physical equations as well as setting up laboratory ...

This work aims to gain a better understanding of how the rheological properties of printable materials affect their processability, as well as the quality of the final product, which at the end can lead to reducing time ...

This paper is concerned with a numerical study on the behavior of a single Newtonian droplet suspended in another Newtonian fluid, all subjected to a simple shear flow. Conservative finite-volume approximation on a collocated ...

This paper is concerned with numerical solution of fluid-structure interaction (FSI) problems involving an incompressible viscous flow and an elastic structure. A second-order time accurate semi-implicit method is proposed ...
