  2. 1. Desalination using Membrane Distillation : Experimental and Numerical Study

    Author : Alaa Kullab; Andrew Martin; Mohammed Khayet; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Air gap membrane distillation; applications; experimental and simulation; CFD; physical modification; performance improvement;

    Abstract : Desalination has been increasingly adopted over the last decades as an option, and sometimes as a necessity to overcome water shortages in many areas around the world. Today, several thermal and physical separation technologies are well established in large scale production for domestic and industrial purposes. READ MORE

  4. 2. Multiphysics modelling of PEM fuel cells - with reacting transport phenomena at micro and macroscales

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; macroscale; PEM fuel cells; CFD; microscale; multiphysics; multiphase; anisotropy;

    Abstract : This thesis presents numerical simulations of reacting transport phenomena in polymer electrolyte membrane (PEM) fuel cells. Broadly, the presented work is subdivided into macro and microscale simulations. READ MORE

  5. 3. Blood flow and cell transport in arteries and medical assist devices

    Author : Niclas Berg; Lisa Prahl Wittberg; Laszlo Fuchs; Mihai Mihaescu; Alessandro Veneziani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodynamics; CFD; Artherosclerosis; Thrombosis; Platelet activation; Hemorheology; Platelet margination; Technology and Health; Teknik och hälsa;

    Abstract : The cardiovascular system is responsible for transport of nutrients, oxygen, as well as the cells and molecules making up the immune system. Through the hemostatic system, the body maintains the integrity of the blood vessels, and prevents bleeding. READ MORE

  6. 4. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells

    Author : Jinliang Yuan; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEMFC.; SOFC; CFD; Duct; Transport Process; Fuel Cell; Heat Transfer; Gas Flow; Numerical Simulation; Analysis;

    Abstract : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. READ MORE

  7. 5. Computational Analysis and Modeling Techniques for Monolithic Membrane Reactors Related to CO2 Free Power Processes

    Author : Faruk Selimovic; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen Transfer Membrane OTM ; High Temperature Heat Exchanger HTHEX ; Monolithic Heat Exchanger; Advanced Zero Emission Power Plant AZEP ; Mixed Ionic-Electronic Conducting Membranes MIEC ; Computational Fluid Dynamics CFD ;

    Abstract : Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. READ MORE
