  1. 1. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  2. 2. Transfer Printing and Cellulose Based substrates for modern Textile Printing

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Mona Mrad; [2019]
    Keywords : ;

    Abstract : Digital printing technology is a technique that has been growing since the 1990s and has a high growth potential when it comes to using different ink types and transfer printing techniques. In comparison to screen printing, digital transfer printing techniques have shown to consume less ink and water and are therefore considered to be a more environmentally friendly alternative for textile printing.

  3. 3. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE

    Abstract : This thesis investigates the possibility to evaluate the film cooling thermal performance on flat plate using Thermochromic Liquid Crystal. After an introduction of the basic concept and background of gas turbine blades film cooling and Thermochromic Liquid Crystal, a thorough explanation of four methods is presented. READ MORE

  5. 5. Full Cycle Cylinder State Estimation in DI Engines with VVA

    University essay from Linköpings universitet/Fordonssystem

    Author : Linus Johansson; [2019]
    Keywords : VVT; Combustion engine; Thermodynamics; CRB;

    Abstract : Tougher legal demands on pollutions require a better developed understanding of the processes that take place in the cylinder. The thesis contributes with a cylinder model that uses the same set of equations for intake, compression,expansion/combustion and exhaust. READ MORE
