  1. 1. Stochastic Reactor Models for Engine Simulations

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Martin Tunér; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SRM; Stochastic Reactor Model; Engine Simulation; Chemical kinetics; HCCI; Direct injection; Combustion; NVO; Modeling; PDF;

    Abstract : The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. READ MORE

  2. 2. Phenomenology of new Neutral Vector Bosons and Parton Distributions from Hadronic Fluctuations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Ekstedt; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Higgs; Gauge Symmetry; Standard Model; BFKL; PDF; DIS; Beyond the Standard Model; Colliders; Phenomenology; Effective Potential; Anomaly; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. READ MORE

  3. 3. Towards understanding breakage and flow in sublevel caving (SLC) Development of new measurement techniques and results from full-scale tests

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Matthias Wimmer; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. READ MORE

  4. 4. Corrosion of Ferritic Stainless Steel Interconnects for Solid Oxide Cells – Challenging Operating Conditions

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Patrik Alnegren; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cell; SOFC; dual atmosphere; chromium volatilization; high temperature electrolysis; high temperature oxidation; interconnect; SOEC;

    Abstract : Solid oxide cells (SOC) have the potential to revolutionize electricity production by being able to both produce electricity with very high efficiency from a variety of fuels or to produce fuels from electricity and abundant raw materials such as water or carbon dioxide. Some material challenges remain to be solved before large-scale commercialization can be achieved. READ MORE

  5. 5. Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Yajing Wu; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Swirling flow; swirler; vortex breakdown; precessing vortex core PVC ; large eddy simulation LES .;

    Abstract : Popular Abstract in English The concern about pollutant emissions from combustion devices has stimulated the development of modern combustion devices. As one of the major power generation machines, modern gas turbine engine has been designed to run at fuel-lean and premixed mode of combustion in which the combustion temperature is moderate so that NOx emission is low.
