  1. 11. Load following in a Swedish nuclear power plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Jacob Bjurenfalk; [2020]
    Keywords : chemical engineering; nuclear power; load following; process engineering; electricity production; APROS; Simulations; swedish power gird; kemiteknik; Technology and Engineering;

    Abstract : The energy system in Sweden is currently under a great transformation, where the part of weather dependent energy sources, so called intermittent sources, like solar and wind power will get greater share in the total production of electricity while the production from stable energy sources like nuclear power is decreasing. For a long time, the nuclear power have been operating at baseload and the hydropower as flexible, though, due to the change in the current power system, nuclear power plants may need to transit to flexible operation and apply load following.

  3. 12. Die life prediction using High Pressure Die Casting simulations

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Halses Sebastian Sivertsen; [2020]
    Keywords : HPDC; simulations; aluminum alloys; MAGMAsoft;

    Abstract : Global trends in automotive industry for weight reduction drives an interest for casting of structural aluminum parts. High pressure die casting (HPDC) is chosen for this purpose since it enables manufacturing of large series parts where complexity and repeatability is demanded. READ MORE

  4. 13. Predictive Maintenance for RM12 with Machine Learning

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Lotta Karlsson; [2020]
    Keywords : ;

    Abstract : Few components within mechanical engineering possess the fatigue resistance as of high-pressure turbine blades found in jet engines. This as they are designed to perform in extensively high temperatures under severe loading which causes degradation to be an important aspect despite a design, optimized for its environment.

  5. 14. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

    University essay from Jönköping University

    Author : Ruslan Sevastopolev; [2020]
    Keywords : High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

    Abstract : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. READ MORE

  6. 15. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Martin Perkovic; [2020]
    Keywords : Wear; erosion; sliding wear; gun barrel; characterisation;

    Abstract : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. READ MORE
