1. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction
Master-uppsats, KTH/Teknisk mekanikSammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER
2. Utvärdering av möjligheten till energioptimering för pumpning av vitlut för kontinuerlig kokning av sulfatmassa vid Smurfit Kappa Piteå
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : The goal of this thesis is to investigate the optimization possibilities of a white liquor pump in a pulp mill. Through the implementation of a new process solution, the potential energy and financial saving opportunities are analyzed. LÄS MER
3. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. LÄS MER
4. Köldmedieläckage i kylanläggningar : En utredning om alternativa metoder för att detektera läckage
Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknikSammanfattning : Commercial refrigerant industry is one of the biggest contributing factors toglobal warming according to a study by Mota-Babiloni et al. (2015). Studies have shown that emissions of fluorinated greenhouse gases' effect on global warming can increase from 1.3% (2004) to 7. LÄS MER
5. Design of a radial-inflow microturbine for combined heat and power generation unit
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.. LÄS MER
