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

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mario Setta; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  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

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

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

    Abstract : 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. READ MORE

  4. 3. Modelling of spinodal decomposition in the binary Fe-Cr system

    University essay from KTH/Materialvetenskap

    Author : Viking Roosmark; [2016]
    Keywords : SPINODAL DECOMPOSITION; FE-CR; DIFFUSION; FERRITIC STAINLESS STEAL;

    Abstract : Spinodal decomposition is a phenomenon which hinders the usage of ferrite containing steels under certain conditions. With a better understanding and knowledge of spinodal decomposition new ferritic and duplex stainless steels could be designed. The project is divided into two parts, an experimental part and a theoretical part. READ MORE

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

    University essay from Institutionen för fysik

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

    Abstract : 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. READ MORE
