Abstract
Numerical analysis for a two dimensional case of two–phase fluid flow has been performed to investigate the impact, deformation of droplets and filament for printing processes. The purpose of this investigation is to study the phenomenon of liquid droplet and filament impact on a rigid substrate, during various manufacturing processes such as jetting technology, inkjet printing and direct printing. This investigation focuses on the analysis of interface capturing and the change of shape for droplets (jetting technology) and filaments (direct printing) being dispensed during the processes. Investigations have been performed with an adaptive quadtree spatial discretization with geometrical Volume–Of–Fluid (VOF) interface representation, continuum–surface–force surface tension formulation and height-function curvature estimation for interface capturing during the impact and deformation of droplets and filaments. Gerris Flow Solver, an open source finite volume code, has been used for the numerical analysis which uses a quadtree based adaptive mesh refinement for two–dimensional analysis. The numerical model has been validated with literature and experiment. The investigation has been performed for ranges of dimensionless governing parameters.
