  1. 1. Conceptual design and construction of a UAV wing structure

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Selma Rahman; Anujan Ranganathan; [2020]
    Nyckelord :;

    Sammanfattning : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. LÄS MER

  2. 2. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aljaz Janic; [2020]
    Nyckelord :Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Sammanfattning : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. LÄS MER

  3. 3. Simulations of complete vehicles in cold climate at partial and full load driving conditions

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Akshay Jamadagni H N; [2020]
    Nyckelord :Boundary conditions; climatic wind tunnel; computational fluid dynamics; temperature; vehicle thermal management.;

    Sammanfattning : In this study, CFD simulations of a complete truck are carried out to investigate the effect of altered simulation settings at cold climatic conditions. The aim of this study is to obtain knowledge through CFD simulations performed on a selected driving condition namely at a vehicle speed of 93 kph, an ambient temperature of -20 °C and for an engine operating at 25 % load.

  4. 4. Aerodynamic Design in Axial Turbine for Heavy Duty Applications

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Eric Lennman; [2020]
    Nyckelord :Turbine design; MULTALL; Design methodology; Electric turbo compound turbine; Technology and Engineering;

    Sammanfattning : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. LÄS MER

  5. 5. Venturi Undertray : KTH Bachelor Thesis Report

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Författare :Selma Boudali; Mattias Olausson; [2020]
    Nyckelord :Race car aerodynamics; undertray; Venturi effect; Formula student; CFD analysis; Topology optimization.; Aerodynamiken på racerbil; underrede; Venturi effekt; CFD analys; Topologioptimering.;

    Sammanfattning : This bachelor thesis aims to describe the work performed for the design of the undertray for the Kungliga Tekniska Högskolan Formula Student(KTHFS) race car. The goal was to achieve an aerodynamically optimized undertray design that follows the regulations of the competition and the targets set by KTHFS concerning the weight, the size, the materials needed for its manufacture and costs.
