  1. 21. Aerodynamic Design in Axial Turbine for Heavy Duty Applications

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Eric Lennman; [2020]
    Nyckelord :Turbine design; MULTALL; Design methodology; Electric turbo compound turbine; Technology and Engineering;

    Sammanfattning : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. LÄS MER

  3. 22. Parametric Adjoint Optimization of a Twisted Rudder

    Master-uppsats, KTH/Marina system

    Författare :Andreas Hörberg; [2020]
    Nyckelord :Maritime; CFD; Optimization; Adjoint method; Twisted rudder; Sjofart; CFD; Optimering; Adjointmetoden; Tvistat roder;

    Sammanfattning : Optimization methods are commonly used to develop new products and are also an importantstep in more incremental design improvements. In the maritime industry, these methodsare often used to create more ecient vessels and to ful ll the environmental requirementsimposed by the IMO. In recent years, the adjoint method have been used more frequently. LÄS MER

  4. 23. Venturi Undertray : KTH Bachelor Thesis Report

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Selma Boudali; Mattias Olausson; [2020]
    Nyckelord :Race car aerodynamics; undertray; Venturi effect; Formula student; CFD analysis; Topology optimization.; Aerodynamiken på racerbil; underrede; Venturi effekt; CFD analys; Topologioptimering.;

    Sammanfattning : This bachelor thesis aims to describe the work performed for the design of the undertray for the Kungliga Tekniska Högskolan Formula Student(KTHFS) race car. The goal was to achieve an aerodynamically optimized undertray design that follows the regulations of the competition and the targets set by KTHFS concerning the weight, the size, the materials needed for its manufacture and costs.

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

    Master-uppsats, KTH/Fordonsdynamik

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

    Sammanfattning : 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. LÄS MER

  7. 25. Experimental and CFD Study of Heat Pickup in Cooling System Hoses

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :August Borg; Michael Owen; [2019]
    Nyckelord :;

    Sammanfattning : This thesis investigates a process known as heat pickup which occurs in vehicle cooling system hoses. Heat pickup is an unwanted side effect of temperature differences in a car underhood compartment, whereby excess heat is tranferred into the coolant running through the cooling system hoses, affecting its operating temperature.
