* The rotor theories by Professor Joukowsky: Vortex theories: https://lnkd.in/d_SrQabu Abstract: This is the second of two articles with the main, and largely self-explanatory, title “Rotor theories by Professor Joukowsky”. This article considers rotors with finite number of blades and is subtitled “Vortex theories”. The first article with subtitle “Momentum theories”, assessed the starring role of Joukowsky in aerodynamics in the historical context of rotor theory. The main focus in both articles is on wind turbine rotors, but much of the basic theory applies to propellers and helicopters as well. Thus this second article concentrates on the so-called blade element theory, the Kutta–Joukowsky theorem, and the development of the rotor vortex theory of Joukowsky. This article is to a large extent based on our own work, which constitutes the first successful completion and further development of Joukowsky׳s work by deriving the first analytical solution of his rotor. This rotor has a finite number of blades and will be compared with the rotor analysis of Betz and of others of the German school of aerodynamics.

Playing with the Air from last 1.5 years, but now on a bigger screen with a high power workstation. Of course, Aerodynamics is important everywhere if you do not want your power units to be loaded hugely by an invisible force which increases as you speed up. Working on External LES after previously working on Hydrodynamic, Combustion, Supersonic flows and Liquid Propulsion systems.

All aboard! 🚂 Did you know the railway industry was among the first to realize the importance of aerodynamics and drag? In the 1930s, iconic “Streamliner” locomotives such as the American Pioneer Zephyr, British Mallard and German Flying Hamburger reached speeds well over 100 mph thanks mainly to their sleek designs, which reduced drag. Aerodynamics is crucial in developing rail vehicles – drag significantly impacts energy efficiency and fuel consumption even at lower speeds. Computational fluid dynamics (CFD) simulation allows engineers to design trains to minimize air resistance and to analyze aerodynamics long before wind tunnel testing. http://go.3ds.com/EYe

Tomorrow, we'll be happy to introduce a new Axial Fan Acoustic Benchmark. In this project, we deal with the engineering simulation of Computational Aero-Acoustics (CAA), focusing on the Axial Fans. Employing advanced techniques like resolved CFD simulation together with the Acoustic Analogy and Ffowcs Williams-Hawkings, we explore the transient simulation with Finite Volume CFD simulations in a cell-centered framework. The mesh generation utilizes SnappyHexMesh with inflation layers powered by OpenFOAM and within the TCAE environment. Our study employs the k ω SST-DES model. We assess the Sound Pressure Level (SPL), Power Spectral Density (PSD), present Polar plots, and backward sound reconstruction. This comprehensive analysis sheds light on the fascinating world of CAA and its applications in aerodynamics.

Excited to share that I recently conducted a wind tunnel experiment on a wooden airfoil prototype in a subsonic wind tunnel! This project allowed me to apply theoretical knowledge of aerodynamics to real-world testing. The data gathered will be instrumental in optimizing lift and drag characteristics, understanding flow behavior around the airfoil. Looking forward to delving deeper into the results and sharing them soon! #aerodynamics #windtunnelefficiency #prototyping
