  1. 1. Evaluation of a computational method for natural fiber-reinforced plastics

    University essay from KTH/Hållfasthetslära

    Author : Anna Lim; [2023]
    Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

  3. 2. Implementation and study of boundary integral operators related to PDE:s in the plane

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Andersson; [2023]
    Keywords : Boundary integral equation; Singular integral operator; Product integration; Close evaluation; Numerical integration; MATLAB; Mathematics and Statistics;

    Abstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

  4. 3. Air Cooling of Lithium Polymer Batteries : Experiments and Calculations on the KTH Formula Student 2022 Race Car Accumulator

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

    Author : William Olsson; Linus Grinde; [2022]
    Keywords : ;

    Abstract : Lithium batteries work optimally at a temperature of around 15 to 35 °C, with a maximum temperature of around 60 °C. To get the most performance out of a formula student car the cooling needs to keep the battery cells within these temperatures during the competition. READ MORE

  5. 4. Lid driven cavity flow using stencil-based numerical methods

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Hannes Juujärvi; Isak Kinnunen; [2022]
    Keywords : Finite differences; incompressible Navier-Stokes equations; lid driven cavity flow; benchmark problem; RBF-FD-LS; FDM; accuracy; computational cost; stream function-vorticity formulation;

    Abstract : In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity problem. The Navier-Stokes equations is solved using stream function-vorticity formulation. READ MORE

  6. 5. Simulation of Transformer Inrush Currents and Their Impact on the Grid

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Juan de la Peña Toledo; [2022]
    Keywords : Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

    Abstract : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. READ MORE
