  1. 1. Adjoint-based Formulation for Shape Optimization Problems in Computational Fluid Dynamics

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Anton Scotte; [2023]
    Nyckelord :;

    Sammanfattning : A continuous adjoint formulation for exterior optimization of Dirichlet data on the boundary for potential flow applications has been developed in this thesis. This has been performed by utilizing boundary integral methods for both the primal problem (Laplace’s equation) and for the corresponding adjoint equation (Poisson’s equation) on the unit disc.

  3. 2. Adjoint optimization of a liquid-cooled heat sink

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Roven Pinto; [2023]
    Nyckelord :Adjoint method; topology optimization; porosity; OpenFOAM;

    Sammanfattning : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. LÄS MER

  4. 3. Embedded eigenvalues for asymptotically periodic ODE Systems

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Wilhelm Treschow; [2022]
    Nyckelord :embedded eigenvalue perturbation theory ODE theory; Mathematics and Statistics;

    Sammanfattning : In this thesis we investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L^2(\mathbb{R},\mathbb{R}^n), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. LÄS MER

  5. 4. Energy optimization tool for mild hybrid vehicles with thermal constraints

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Chitranjan Singh; Tamas Tamilinas; [2020]
    Nyckelord :Control Systems; Mild Hybrids; Energy Management System; Kinetic Energy Regenerative Systems; Equivalent Consumption Minimization Strategy; Hybrid Powertrain Controls; Kontrollsystem; Milda hybrider; energihanteringssystem; regenererande system för kinetisk energi; Ekvivalent konsumptions-minimeringsstrategi; hybridstyrningskontroll;

    Sammanfattning : The current global scenario is such where impact on the environment is becoming a rising concern. Global automotive manufacturers have focused more towards hybrid and electric vehicles as both more aware customers and governmental legislation have begun demanding higher emission standards.
