  1. 11. Reissner Mixed Variational Theorem for Ritz Sublaminate Generalized Unified Formulation

    University essay from KTH/Lättkonstruktioner

    Author : Pier Antonio Esposito; [2021]
    Keywords : Mechanics; FEM; Ritz; Reissner; Stress; deformations; composite materials; Mekanik;

    Abstract : This thesis is about the development of a new numerical method for the analysis of composite shells. The present work is based on Reissner Mixed Variational Theorem (RMVT), the Sublaminate Generalized Unified Formulation (S-GUF), and the Ritz approximation. READ MORE

  3. 12. Efficient Calculations of Two-Dimensional Radar Cross-Section Using DGFEM

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Daniel Persson; [2020]
    Keywords : numerical methods; DGFEM; discontinuous Galerkin; finite element method;

    Abstract : A two-dimensional discontinuous Galerkin finite element method algorithm in the time domain was developed for calculation of the radar cross-section of an arbitrary object. The algorithm was formed using local nodal basis functions in each element and coupling them via numerical upwind flux. READ MORE

  4. 13. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE

  5. 14. 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. 15. B-plane orbital resonance analysis and applications

    University essay from KTH/Rymdteknik

    Author : Alessandro Masat; [2020]
    Keywords : ;

    Abstract : Many space engineering and orbital mechanics applications seek for the usage of focused mathematical models, capable of providing useful insight onto particular phenomena or exploiting some theoretical and physical tools to reduce the computational costs and/or increase the level of accuracy reached. Orbital resonances are one of the phenomena that needs to be properly modelled, both for exploiting such features in the mission design phase and to predict possible resonant returns of threatening objects closely approaching a specified planet.
