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. Aerodynamics simulations of Scania trucks using OpenFOAM

   University essay from KTH/Teknisk mekanik

   Author : Ziyi Liu; [2024]
   Keywords : Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

   Abstract : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. READ MORE

4. 3. Methods and Purposes of Aerodynamic Correlation in Formula Student

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Alix Le Bastard; [2023]
   Keywords : Technology and Engineering;

   Abstract : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.

5. 4. Efficient FE Modeling of Large Casted Parts

   University essay from KTH/Maskinkonstruktion

   Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
   Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

   Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

6. 5. Modeling for characterization of continuous casting simulator using CFD

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

   Author : Filip Reineholm-Hult; [2023]
   Keywords : Continuous casting; CFD; computational fluid dynamics;

   Abstract : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. READ MORE
