  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

  3. 2. The influence of soil modeling on the prediction of vehicle dynamics and mobility – A comparison between the Finite Element Method and a Semi[1]Empirical Model

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jimmy Kjellqvist; [2023]
    Keywords : ;

    Abstract : This master's thesis investigated the influence of soil modeling on vehicle dynamics and mobility predictions with a focus on two different soil models implemented in Project Chrono: the Bekker-Wong model, and a Finite Element (FE) model. The primary objective is to provide insights for decision-making regarding the most suitable soil model under specific circumstances. READ MORE

  4. 3. Acoustic Prediction Methods for Rocket Flame Deflector Design

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

    Author : FREDRIK RANOW; [2021]
    Keywords : Flame deflector; Launch pad; Estimation methods; Acoustics; Reflectivity; Diffraction; Directivity; Flamdeflektor; Uppskjutningsplattform; Uppskattningsmetoder; Akustik; Reflektivitet; Diffraktion; Direktivitet;

    Abstract : The aim of the project behind this report is to gain an understanding for the design criteria of launch pad flame deflectors used for launching rockets. This report presents an overview of the underlying phenomena, and then tackles the issue of estimating noise levels that come about during lift-off. READ MORE

  5. 4. 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. 5. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vilhelm Ekberg; [2019]
    Keywords : anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Abstract : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. READ MORE
