  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  2. 2. 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

  3. 3. Investigation of open-Source CFD software on shipyards - Analysis of combustion outlets on large yachts using openFoam®

    University essay from

    Author : Carl Jascha Mordhorst; [2019-07-03T12:39:50Z 2019-07-03T12:39:50Z 2011]
    Keywords : Transport; Farkostteknik; Transport; Vehicle Engineering;

    Abstract : Abstract Modern engineering requires detailed knowledge of forces, flow directions and velocities, when designing the vehicles of the future. In the ship building industry this is traditionally done in towing tank and wind tunnel experiments or by the long experience of skilled engineers. READ MORE

  4. 4. Efficient seakeeping performance predictions with CFD

    University essay from KTH/Marina system

    Author : Benjamin Lagemann; [2019]
    Keywords : added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

    Abstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE

  5. 5. Parametric Hull Form Variation and Assessment of Seakeeping Performance

    University essay from KTH/Marina system

    Author : Aina Pons Roser; [2018]
    Keywords : ;

    Abstract : This Master Thesis is about the assessment of the seakeeping performance of different ships subjected to hull parametric variations. The latest version of the potential flow CFD software Shipflow in combination with a CAD platform (CAESES) have been used to carry out the evaluations. READ MORE
