  1. 1. Numerical investigation on the effects of out-of-flatness on leakage in metal-to-metal seals

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lumi Canhasi; [2017]
    Keywords : ;

    Abstract : Since the usage of pressurized systems, there has been a challenge to prevent and control leakage of different fluids. When a metal-to-metal face seal is designed, different aspects are to be considered. Its ring shaped sealing surface is designed to prevent leakage and also to maintain pressure. READ MORE

  2. 2. Developing a Mounting Tool for Magnetic Poles in the Stator of a new Wave Power Generator : Mounting Tool for Magnets

    University essay from KTH/Industriell ekologi; KTH/Industriell ekologi

    Author : Alexander Isakson; Simon Lundgren; [2017]
    Keywords : ;

    Abstract : At KTH Royal Institute of Technology, a novel type of transverse flux generator aimed for ocean wave energy conversion is being developed. This machine is complex to assemble, and the aim of this project was to develop a tool to aidin mounting neodymium magnets, fixed in rows, next to each otherto create a single magnetic pole.

  3. 3. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Tetsuro Goda; [2017]
    Keywords : Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Abstract : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. READ MORE

  4. 4. Thermal Analysis of a Sea Wave Generator

    University essay from KTH/Elkraftteknik

    Author : Ezequiel Quijada; [2017]
    Keywords : sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

    Abstract : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.

  5. 5. Ocean Waves Estimation : An Artificial Intelligence Approach

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Andreas Ramberg; [2017]
    Keywords : Artificial Intelligence; Case-Based Reasoning; Encounter Angle; Encounter Spectrum; Feedforward Neural Network; Genetic Algorithm; Inverse Problem; Marine Vessels; Master Thesis; MATLAB; Model Parameter Estimation; Ocean Theory; Peak Period; Response Amplitude Operator; Ships; Significant Wave Height; Transfer Function; Wave Spectrum; Waves;

    Abstract : This thesis aims to solve the mathematical inverse problem of characterizing sea waves based on the responses obtained from a marine vessel sailing under certain sea conditions. By researching this problem the thesis contributes to the marine industry by improving products that are using ocean behavior for controlling ship's dynamics. READ MORE
