1. 1. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing

   Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Författare :Mario Setta; [2021]
   Nyckelord :;

   Sammanfattning : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. LÄS MER

3. 2. Morphology formation via a ternary Cahn-Hilliard system during one species evaporation as a moving boundary problem - Finite Element approximation and implementation in FEniCS

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :Nicklas Jävergård; [2020]
   Nyckelord :Morphology Formation; Evaporation; Cahn Hilliard Equations; Finite Element Method; Morforlogiformation; avdunstning; Cahn-Hilliards ekvation; Finita element metoden;

   Sammanfattning : In this thesis we derive a coupled system of Cahn-Hilliard equations posed in a domain with moving boundary using arguments from thermodynamics. The physical setting we have in mind is a ternary solution observed during one species evaporation as a moving boundary problem. LÄS MER

4. 3. Simulation of a multi phase flow in a rotating-lid driven cylinder

   Master-uppsats, Institutionen för fysik

   Författare :Mats Johansson; [2013]
   Nyckelord :Navier-Stokes; Cahn-Hilliard; Flow; Cylinder; Multi Phase;

   Sammanfattning : This report describes the development of a software for computing viscous incompressiblemultiphase ows. The software does this with solving the coupled non-linear Navier-Stokes(Fluid) and the Cahn-Hilliard (Phase-Field) equations using a Finite Element Method. LÄS MER
