  1. 41. Nonlinear Methods of Aerodynamic Data-driven Reduced Order Modeling

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Arvid Forsberg; [2022]
    Keywords : machine learning; aerodynamics; autoencoder; kernel transformation; principal component analysis; nonlinear; regression; modeling; surrogate model; reduced order modeling; neural network;

    Abstract : Being able to accurately approximate outputs of computationally expensive simulations for arbitrary input parameters, also called missing points estimation, is central in many different areas of research and development with applications ranging from uncertainty propagation to control system design to name a few. This project investigates the potential of kernel transformations and nonlinear autoencoders as methods of improving the accuracy of the proper orthogonal decomposition method combined with regression.

  3. 42. 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

  4. 43. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aniruddh Mohan; [2022]
    Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

    Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE

  5. 44. Improvement of the 1D CFD method for Thermal management of a Battery Electric Vehicle

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : SASHWAT CHHETRI; [2022]
    Keywords : CFD; Electromobility; BEV; Thermal Management; Simulation;

    Abstract : Electrification of vehicles is necessary to combat greenhouse gas emissions, whichcauses global warming and climate change. There has been a demand in the use ofBattery Electric Vehicles due to this increased awareness of sustainability. However,they have been beset with issues such as range and conservation of energy.

  6. 45. Turbo For Fuel Cell Electric Vehicle

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Adam Hansson; Mohammed Abu Al-Soud; [2022]
    Keywords : Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

    Abstract : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. READ MORE
