  1. 21. CFD Optimization of Hydrofoiling Concept for A New Era of Sea Transports

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

    Author : Anlun Li; [2022]
    Keywords : Optimization; Hydrofoil; FoilCart; Transportation; CFD; Optimering; Hydrofoil; FoilCart; Transport; CFD;

    Abstract : The aim of this master thesis is to develop and optimize the main wing of a T-shaped hydrofoil for a small passenger vessel called FoilCart. The project is in collaboration with KTH Maritime Robotic Lab. The existing prototype of the hydrofoil is built by a company called ZPARQ\cite{Zparq}, but the efficiency of the main wing is not optimized. READ MORE

  3. 22. Multibody modelling of the vibrations in an aircraft engine

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

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

  4. 23. Aeroengine transients in altitude test facility

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

    Author : Baptiste VILLENEUVE; [2022]
    Keywords : ;

    Abstract : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. READ MORE

  5. 24. Modelling and Simulation of Complete Wheel Loader in Modelica : Evaluation using Modelon Impact software

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

    Author : Paolo Teta; [2022]
    Keywords : Modelica; Wheel Loader; Mechanics; Object-orientation; Modelling; Simulation; Differential Algebraic Equations; Ordinary Differential Equations; Modelica; Hjullastare; Mekanik; Objektorientering; Modellering; Simulering; Differentialekvationer;

    Abstract : Modelling and simulation of complex and multi-domain mechanical systems has become of major importance in the last few years to address energy and fuel consumption performance evaluation. The goal is to unify the available modelling languages aiming to improve scalability and easiness of handling complex multi-domain models. READ MORE

  6. 25. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Linnéa Tebelius; [2022]
    Keywords : Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Abstract : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.
