1. 1. Wall-Resolved and Wall-Modelled LES for a NACA4412 Wing Profile in OpenFOAM

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Nikolaos Charisoudis; [2024]
   Keywords : ;

   Abstract : The purpose of this study is to perform computational fluid dynamics (CFD) simulationfor an incompressible flow around an airfoil and investigate the aerodynamicproperties for different Reynolds numbers (400, 000 and 1, 000, 000) based on the chordlength, at the moderate angle of attack (AoA) of 5o . For this purpose a detailedevaluation of wall-resolved and wall-modelled large-eddy simulations (LES) wereconducted for the NACA4412 wing profile. READ MORE

3. 2. Thermal and flow field validation of lattice Boltzmann method solver

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : André Skagius-Kallin; [2023]
   Keywords : Lattice Boltzmann method; heat transfer; flow field;

   Abstract : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. READ MORE

4. 3. Influence of structural complexity of the Rumperöd forest on evapotranspiration

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Madeleine Durdek; [2023]
   Keywords : Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

   Abstract : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. READ MORE

5. 4. CFD investigation of a unit cell inside a Plate Heat Exchanger

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Mattias Ly; [2023]
   Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Abstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

6. 5. EXPLORING THE IMPACT OF INFLUENCER MARKETERS ANDFOLLOWERS ON GHANAIAN TELECOMMUNICATION BRANDS

   University essay from Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

   Author : Emmanuel Eddy Botchway; [2023]
   Keywords : Influencer marketing; Social media; Telecommunication; Marketing;

   Abstract : The telecommunication industry in Ghana forms one of the mainline business industries that play a key role in the country’s economic stability. At the heart of this industry are two giant brands; MTN and Vodafone, who hold sway on the market share. READ MORE
