2. 6. Simulations of compressible flows associatedwith internal combustion engines

   Author : Olle Bodin; Laszlo Fuchs; Mihai Mihaescu; Michael Leschziner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Gas exhange; exhaust port; exhaust manifold; POD; DMD; exhaust; LES; Gasväxling; avgasport; avgasgrenrör; POD; DMD;

   Abstract : Vehicles with internal combustion (IC) engines fueled by hydrocarbon compoundshave been used for more than 100 years for ground transportation.During these years and in particular the last decade, the environmental aspectsof IC engines have become a major political and research topic.

4. 7. Computation and Analysis of EGR Mixing in Internal Combustion Engine Manifolds

   Author : Alexander Sakowitz; Laszlo Fuchs; Angelo Onorati; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Mixing; Large Eddy Simulation; URANS; Internal Combustion Engines; Intake Manifolds; T-junction; Exhaust Gas Recirculation;

   Abstract : This thesis deals with turbulent mixing processes occurring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. READ MORE

5. 8. On the Computation of Turbulent Mixing Processes with Application to EGR in IC-engines

   Author : Alexander Sakowitz; Laszlo Fuchs; Michel Cervantes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Mixing; Large Eddy Simulations; IC-engines; T-junction;

   Abstract : This thesis deals with turbulent mixing processes occuring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. READ MORE

6. 9. Musculoskeletal Biomechanics in Cross-country Skiing

   Author : L. Joakim Holmberg; Anders Klarbring; Hans-Christer Holmberg; Anders Eriksson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Why copy the best athletes? When you finally learn their technique, they may have already moved on. Using muscluloskeletal biomechanics you might be able to add the "know-why" so that you can lead, instead of being left in the swells. READ MORE

7. 10. Thermomechanical Modelling of Tribological Systems

   Author : Niclas Strömberg; Alain Curnier; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The present thesis concerns the thermomechanical modelling of contact, friction and wear. Within a framework of continuum thermodynamics, Signorini's contact conditions, Coulomb's law of friction and Archard's law of wear are derived by means of a free energy and a dissipation potential.
