  1. 21. On the Fourier Collocation Method

    University essay from Lunds universitet/Matematik LTH

    Author : Henrik Lindell; [2018]
    Keywords : Numerical Analysis; PDE; Partial Differential Equations; Numerical Linear Algebra; Mathematics; Fourier; Collocation; Numerical; Linear Algebra; Mathematics and Statistics;

    Abstract : This BSc thesis focuses on trying to find approximate solutions to partial differential equations using the Fourier collocation method. This method uses Fourier basis functions to approximate the solution to a partial differential equation with periodic boundary conditions. READ MORE

  3. 22. Experimental assessment of fluid hammer prediction algorithms

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Jessica Kihlström; [2018]
    Keywords : ;

    Abstract : Fluid hammer is a problem, which may lead to catastrophic consequences and many engineers have a deficiency in competence when it comes to its prediction. This study´s objective is to assess various fluid hammer prediction models, to evaluate how substantial pressure thrusts would affect a system and to verify the analytical results toward experimental data.

  4. 23. Settlement calculation for lime/cement column improved clay : Analytical and numerical analyses related to a case study

    University essay from KTH/Jord- och bergmekanik

    Author : Hulumtaye Kefyalew Yederulh; [2018]
    Keywords : LCC; deep mixing; consolidation settlement; rate of consolidation; numerical analysis; analytical analysis; field measurement.; KC-pelare; djupstabilisering; konsolideringssättningar; konsolideringsgrad; numerisk analys; analytisk analys; fältmätningar;

    Abstract : The dry deep mixing method is widely used to improve a soft clay soil to increase the shear strength as well as to reduce the time for consolidation. It is a mechanical mixing process that makes parts of the soil stiffer than its original strength. It is mainly applicable to soft clay or peat soil. READ MORE

  5. 24. Determination of the Orbit and Dynamic Origin of Meteoroids

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jennifer Andersson; [2018]
    Keywords : ;

    Abstract : One method that can be used to identify the dynamic origin and specific parent bodies of Earth crossing meteoroids is the determination of the meteoroids’ orbital evolution. In this study, a Python-based program using the REBOUND software integration package to integrate meteoroid orbits backwards in time is developed. READ MORE

  6. 25. Study of tip clearance flows

    University essay from KTH/Flygdynamik

    Author : Camille Fournis; [2018]
    Keywords : turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

    Abstract : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. READ MORE
