  1. 16. Transient thermal management simulations of complete heavy-duty vehicles

    University essay from KTH/Mekanik

    Author : Einar Svantesson; [2019]
    Keywords : Transient; Time-resolved; Vehicle thermal management; Complete vehicle; Dynamic boundary conditions; Drive cycle; Hot shutdown; Heat soak; Heavy-duty vehicles; Heavy trucks; Thermal scale factor; Quasi-transient; Computational fluid dynamics.;

    Abstract : Transient vehicle thermal management simulations have the potential to be an important tool to ensure long component lifetimes in heavy-duty vehicles, as well as save development costs by reducing development time. Time-resolved computational fluid dynamics simulations of complete vehicles are however typically very computationally expensive, and approximation methods must be employed to keep computational costs and turn-around times at a reasonable level.

  3. 17. Influence of inflow conditions on simulations of arterial blood flow

    University essay from KTH/Mekanik

    Author : Marcus Strimell Flodkvist; [2018]
    Keywords : ;

    Abstract : The blood is responsible for the oxygenation of the body and to carry nutrients to the different parts of the body and waste products away from the major organs like the liver, kidneys but also the walls of the arteries. Blood is composed of red blood cells that are on average 45% of the total volume, the rest of the blood is made up of blood plasma platelets, white blood cells, minerals and nutrients. READ MORE

  5. 19. Numerical Model of MeltingProblems

    University essay from KTH/Mekanik

    Author : Arturo Arosemena; [2018]
    Keywords : Phase change materials; fluid dynamics; heat transfer; natural convection; melting; enthalpy-porosity technique.;

    Abstract : In the present study, a finite volume method is employed to modelthe advection-diffusion phenomenon during a pure substance meltingprocess. The exercise is limited to a benchmark problem consisting ofthe 2D melting from a vertical wall of a PCM driven by natural convectionin the melt. READ MORE

  6. 20. Investigation of performance and surge behavior of centrifugal compressors through CFD simulations

    University essay from KTH/Mekanik

    Author : Francesco Tosto; [2018]
    Keywords : centrifugal compressor; Computational Fluid Dynamics CFD ; RANS; surge; compressible uid dynamics; Design of Experiments DoE .; centrifugalkompressor; CFD-simulering; RANS; overskott; komprimerbar vatskedynamik; Design of Experiments DoE ;

    Abstract : The use of turbocharged Diesel engines is nowadays a widespread practice in the automotive sector: heavy-duty vehicles like trucks or buses, in particular, are often equipped with turbocharged engines. An accurate study of the flow field developing inside both the main components of a turbocharger, i.e. READ MORE
