  1. 1. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Huanyu Chen; [2022]
    Keywords : CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

    Abstract : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

  3. 2. Error estimation for neural network approximations of convection problems

    University essay from KTH/Matematik (Avd.)

    Author : Ludvig Eidmann; [2022]
    Keywords : ;

    Abstract : The problem of approximating a solution to the convection equation $\partial_t u +f\cdot\nabla_xu = h$ given data on the flux $f$, source function $h$ and a final condition $g$ is investigated. Specifically, two layer neural networks are used to approximate $f,h$ and $g$ and a solution is approximated using numerical integration. READ MORE

  4. 3. Conservative Discontinuous Cut Finite Element Methods: Convection-Diffusion Problems in Evolving Bulk-Interface Domains

    University essay from KTH/Matematik (Inst.)

    Author : Sebastian Myrbäck; [2022]
    Keywords : numerical analysis; mathematical modeling; convection-diffusion equation; partial differential equation; unfitted method; CutFEM; finite element method; discontinuous Galerkin method; numerisk analys; matematisk modellering; konvektions-diffusionsekvationer; partiella differentialekvationer; finita elementmetoden; diskontinuerliga Galerkinmetoden;

    Abstract : This work entails studying unfitted finite element discretizations for convection-diffusion equations in domains that evolve in time. In particular, these partial differential equations model the evolution of the concentration of soluble surfactants in bulk-interface domains. READ MORE

  5. 4. Ultrasonic Assisted Drying and its Effect on 3D Printability of Minced Beef and Other Foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Viktor Lindström; [2020]
    Keywords : Drying; Convection drying; Ultrasound; Ultrasonic drying; 3D-Printing; 3D-Printability; Food; Meat; Beef; Food technology; Livsmedelsteknologi; Technology and Engineering;

    Abstract : The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. READ MORE

  6. 5. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Rydgård; [2020]
    Keywords : lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. READ MORE
