  1. 16. Evaluation of drag estimation methods for ship hulls

    University essay from KTH/Mekanik

    Author : Hampus Tober; [2020]
    Keywords : ;

    Abstract : This study aims to evaluate to which degree CFD can complement traditional towing-tank experiments, and to develop a computationally cheap and robust methodology for these type of simulations. Two radically different surface ship hulls were chosen for the trials: a capesize bulk carrier and a fast displacement hull. READ MORE

  3. 17. Experimental study on stepped spray deflectors for planning hull

    University essay from KTH/Marina system

    Author : Luca Castaldi; [2020]
    Keywords : ;

    Abstract : Planning vessels can reach high operational speeds thanks to their hull design. Some hull forms will develop large volumes of spray attached to the hull surface. The whisker spray is a thin layer consisting in droplets of water which can ac-count for a large proportion of the total resistance. READ MORE

  4. 18. Estimating Charging on a Sounding Rocket Experiment Using Plasma Simulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emelie Modin; [2020]
    Keywords : Current Voltage Characteristics; SoundingRocket; SPIDER-1; SPIDER-2; Aurora; SPIS;

    Abstract : The aim of this project is to model current volt-age characteristic curves for different plasma conditions (i.eelectron density, electron temperature, ion temperature andplasma potential) that can be found in active auroras. This isdone by simulating the charging of a FFU with a connectedLangmuir probe in the software SPIS. READ MORE

  5. 19. Methods to Predict Hull Resistance in the Process of Designing Electric Boats

    University essay from KTH/Marina system

    Author : Felicia Ahlstrand; Elin Lindbergh; [2020]
    Keywords : ;

    Abstract : Combustion engines in boats cause several environmental problems, such as greenhouse gas emissions and acidication of oceans. Most of these problems can be reduced by replacing the combustion engines with electric boats. READ MORE

  6. 20. Study of semi-empirical methods for ship resistance calculations

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Emil Petersson; [2020]
    Keywords : ;

    Abstract : In the early ship design process a quick overview of which shipdesign that could be the optimal choice for the intended usage needsto be investigated. Therefore the feasibility and accuracy ofinterpolating between measurement data from model resistance serieswhen estimating unknown hulls were conducted. READ MORE
