  1. 1. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

    University essay from KTH/Jord- och bergmekanik

    Author : Roaa Al Omari; Yasmeen Alali; [2021]
    Keywords : ;

    Abstract : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. READ MORE

  3. 2. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Francesca Polato; [2021]
    Keywords : hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Abstract : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

  4. 3. The verification and validation of a probabilistic risk analysis method for road tunnels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Kim Genberg; Karin Sandin; [2020]
    Keywords : Tunnels; fire; evacuation; probabilistic risk analysis; QRA; verification and validation; Technology and Engineering;

    Abstract : In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled.

  5. 4. Implementation, Validation, and Evaluation of 1D-3D CFD Co-simulation for Cooling System of Internal Combustion Engine

    University essay from KTH/Fordonsdynamik

    Author : Amirali Kerachian; [2020]
    Keywords : CFD; 1D-3D Co-simulation; Cooling Systems; Turbulence Modeling; CFD; 1D-3D Co-simulering; kylsystem; turbulensmodellering;

    Abstract : Internal combustion engines, electric motors and batteries generate a significant amount of heat during operation that needs to be extracted by cooling systems. A cooling system is designed and installed to extract the generated heat and maintain the system temperature in an optimal range. READ MORE

  6. 5. 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.
