  1. 1. Modeling of the trajectory of ice thrown from a wind turbine

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Elena Rocchi; [2023]
    Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

    Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

  3. 2. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  4. 3. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    University essay from KTH/Teknisk mekanik

    Author : Joseph Vernier; [2023]
    Keywords : Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Abstract : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. READ MORE

  5. 4. Effects of surface roughness on spillway flow behaviors

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Oday Asalya; Joar Fjällborg; [2023]
    Keywords : CFD; ansys fluent; roughness height; ytråhet;

    Abstract : This thesis examines the impact of spillway surface roughness on discharge capacity determination in hydraulic models. The study combines physical hydraulic modeling in a laboratory with Computational Fluid Dynamics (CFD) modeling using Fluent. READ MORE

  6. 5. Rocket Jet Impinging on a Surface

    University essay from KTH/Teknisk mekanik

    Author : Javier Capel Jorquera; [2022]
    Keywords : Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Abstract : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. READ MORE
