1. 6. Performance improvement from single to multi phase change materials in a thermal energy storage system

   University essay from KTH/Energiteknik

   Author : Randén Hampus; [2015]
   Keywords : ;

   Abstract : Phase change materials are used in many applications to work as thermal energy storage systems. One way to transfer the heat is by letting water flow through a finned pipe submerged in i tank filled with PCMs. This model is analyzed with a finite element difference  based numerical software.

3. 7. Wet Gas Compression - Effects of a liquid phase on radial compressor performance

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Matilda Svensson; [2014]
   Keywords : Thermodynamic model; Centrifugal compressor; Compression; Liquid; Gas; Wet; Wet Gas; Technology and Engineering;

   Abstract : The aim of the Master Thesis is to analyse the state of the art in wet gas compression, wet gas modelling, derive a thermodynamic model for a compressor layout and compare the model to test data. Wet gas compression is a discussed topic within the oil and gas business. READ MORE

4. 8. An Experimental Study of Fibre SuspensionFlows in Pipes using Nuclear MagneticResonance Imaging

   University essay from KTH/Mekanik

   Author : Masato Hirota; [2013]
   Keywords : Fibre suspension; Multi-phase flow; Nuclear magnetic resonance;

   Abstract : This study deals with fibre suspension flows through cylindrical pipes. Thepresent work aims at measurements of opaque flows, which are common inindustries. Nuclear magnetic resonance imaging (NMRI) and ultrasound velocimetryprofiling (UVP) were employed as non-invasive and optic-independenttools to measure the velocity profiles. READ MORE

5. 9. 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

6. 10. Implementation of a standard level set method for incompressible two-phase flow simulations

   University essay from Avdelningen för teknisk databehandling

   Author : Niklas Johansson; [2011]
   Keywords : level set method; incompressible two-phase flow; reinitialization; finite element method; deal.II;

   Abstract : The level set method is a powerful way of tracking surfaces by defining the surface as a zero level set of a continuous function that is usually a signed distance function. The level set method is one of the best methods for simulating multi-phase flow because it can easily handle fast topological changes, as well as splitting and merging of fluids. READ MORE
