  2. 1. Influence of Composition and Pore Geometry on Immiscible Fluid Flow through Greensands: Development of Neutron Transmission Methods and Image Analysis

    Author : Mikael Solymar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pore geometry; image analysis; fluid flow; petrography; greensand; porosity; glauconite; permeability; neutron transmission methods; fluid saturation;

    Abstract : The effect of the mineralogical composition and pore geometry of sediments on the distribution as well as the flow of immiscible fluids are of importance when evaluating petroleum reservoirs. Greensand containing the clay mineral glauconite is a complex reservoir rock type. READ MORE

  4. 2. 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

  5. 3. Computational Analysis of Heat Transfer and Fluid Flow with Relevance for IC-Engine Cooling

    Author : Sassan Etemad; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; turbulence models; Heat transfer; curved duct; secondary flow; IC-engine cooling; Gases; Thermal engineering; applied thermodynamics; Teknik; Technological sciences; plasma; Gaser; fluiddynamik; plasmas; fluid dynamics;

    Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE

  6. 4. Miniaturized fluid system for high-pressure analytics

    Author : Simon Södergren; Klas Hjort; Sami Franssila; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure; Microfluidics; Thermal regulation; Fluid mechanics; In-situ sensors; High-pressure analytics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).
