1. Modeling of the trajectory of ice thrown from a wind turbine
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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.

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
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : 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. LÄS MER
3. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate
Master-uppsats, KTH/Teknisk mekanikSammanfattning : 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. LÄS MER
4. Effects of surface roughness on spillway flow behaviors
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : 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. LÄS MER
5. Rocket Jet Impinging on a Surface
Master-uppsats, KTH/Teknisk mekanikSammanfattning : 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. LÄS MER
