  1. 11. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Balaji Srinivasan Venkatesan; [2020]
    Keywords : 1-D simulation; System simulation; ROMAX Energy; LMS AMESim; Power loss; Hypoid gear; Power Transfer Unit; Efficiency and Drag Loss Tests; 1-D simulering; systemsimulering; ROMAX Energy; LMS AMESim; effektförlust; hypoidväxel; kraftöverföringsenhet; effektivitet och dragförlusttester;

    Abstract : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

  3. 12. Development of evaluation tools as an approach to pre-design district energy systems : Qualitative modeling and performance simulation using OpenModelica

    University essay from KTH/Energiteknik

    Author : Ghazal Faramarzi; Malin Torestam; [2020]
    Keywords : Heat pump; Thermal energy storage; District heating; Integrated energy system; District energy system; Heating demand; OpenModelica; Planning tool; Qualitative model; CO2 emissions; Techno-economic performance; Swedish energy market; Värmepump; Värmelagring; Fjärrvärme; Integrerade energisystem; Energisystem i stadsdelar; Värmebehov; OpenModelica; Planeringsverktyg; Kvalitativ modell; CO2 utsläpp; tekno-ekonomisk prestanda; Svensk energimarknad;

    Abstract : Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. READ MORE

  4. 13. Automated climate calculations and 3D value-based visualizations : An Integration of BIM and LCA

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : José Arturo Leon Perlasca; [2019]
    Keywords : Building Information Modelling BIM ; Life Cycle Assessment LCA ; Data Visualization; Carbon footprint; Automated climate calculations; Building Information Modeling BIM ; livcykel analys LCA ; datavisualisering; koldioxidavtryck; automatiserad klimatberäkningar;

    Abstract : The Swedish Government has set a goal to reach net zero emissions of greenhouse gases by 2045, which together with the commissioning to the Swedish Housing Agency to prepare requirements for a climate declaration that shall reduce the climate impact from buildings, has enforce the AEC industry to provide solutions that help reach these targets. The introduction of the integration of BIM technologies, together with the LCA methodology has been suggested as a key solution to solve this problem. READ MORE

  5. 14. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Erik Edin; Mattias Ström; [2019]
    Keywords : FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Abstract : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. READ MORE

  6. 15. Thermal modeling of power electronic components in excitation systems

    University essay from

    Author : Fredrik Widberg; [2019]
    Keywords : Excitation systems; Power electronics; Thermal modeling;

    Abstract : This thesis work aims at developing a model in Visual Basic for Applications and Microsoft Excel that can be used to predict temperatures in semiconductor devices for two commercial products made by Voith Hydro AB, and via simulation of the model determine the maximum current that can be conducted through the two products. The two products are called field exciters. READ MORE
