1. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers
University essay from KTH/Teknisk mekanikAbstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE

2. Interscale transport of Reynolds stresses in wall-bounded flows
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.

3. Numerical simulations of mixing for gas exhaust treatment
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. READ MORE

5. Investigating the influence of farm layout on the energy production of simple wind park configurations
University essay from KTH/Kraft- och värmeteknologiAbstract : The interaction between wind turbines in simple wind farm layouts is investigated with the purpose of observing the influence of wake loss phenomenon on the energy production of downwind turbines. Following an intensive exploration stage about wind farm aerodynamics and wake modeling subjects, several tests cases are designed to represent various wind farm configurations, consisting of different number of wind turbines.
