(1) The family of k-ε turbulence models still remains among the most popular turbulence models for industrial applications. (2) Most known and recognized among this family of turbulence models is the Jones-Launder k-ε turbulence model. (3) The model supplies the flow equations with two additional partial differential turbulence equations. One for the turbulence kinetic energy and the other for its dissipation for the modeling of the entire turbulent flow field. (4) The model is in this sense closed (i.e. no flow parameters are specified a priori besides calibration constants). The following SlideShare from "AllAboutCFD" is a concise yet informative and communicated summary on the application of the k-ε model. It is based on "AllAboutCFD" post: "Understanding The k-ε Turbulence Model" - https://lnkd.in/eBRieUQU #turbulence #fluidmechanics #fluidynamics #aerodinamics #engineering

Boundary layer transition is of crucial importance when it comes to predicting the overall performance of turbomachine components. Accurate prediction of the boundary layer transition is therefore an essential aspect of modern research. While standard methods used in industry use models to predict the boundary layer transition (which they can indeed do very well by now), a detailed analysis of the physical phenomena involved is possible mainly with the help of scale-resolving methods. I generated the results shown here by the application of a Large Eddy Simulation (LES). It shows the flow around a modified T106 profile under periodic wake influence (modelled by a rotating bar grid). The isosurface shows the Q-criterion which allows to visualize the state of the boundary layer. In the background the fluctuation velocity is shown, which mainly illustrates the influence of the incoming wakes. A synthetic turbulence generator has been used at the inlet, which ensures both the overall free stream turbulence and the turbulence generated by the inlet guide vane grid. Enjoy how the boundary layer state is fluctuating due to the periodical impact of the incoming wakes changing from (laminar -> turbulent, via laminar separation bubble) to beeing completely turbulent (via wake induced bypass transition)! #srs #les #tecplot #turbulence #transition #cfd #turbine #cfd

💡 #Highcitedpaper 🌊 Title: A Review of High-Fidelity Computational Fluid Dynamics for Floating Offshore Wind Turbines 🔑 Keywords: #floatingoffshore #windturbines; #computationalfluiddynamics; fully coupled performance;  #actuator models; #blade deformations 🔗 Link: https://lnkd.in/gcUNnRbV 📜 Abstract: The design and development of floating offshore wind turbines (FOWTs) is an attractive issue in the wind energy harvesting field. In this study, the research related to the high-fidelity computational fluid dynamic simulations of FOWTs is comprehensively summarized and analyzed. Specifically, the component-level studies including aerodynamics, aeroelasticity and hydrodynamics are presented. The system studies with increasing complexity are performed, such as the simplified aerodynamics, prescribed platform motions and fully coupled aero-hydrodynamics, as well as a little knowledge relevant to the aero-hydro-elastic behaviors. This study emphasizes that some efforts should shift to the research on strongly coupled aero-hydro-elastic performance of FOWTs with the increasing rotor diameter. Moreover, further investigations of more realistic atmospheric inflows and strong interactions between multi-FOWTs are required. This study aims to introduce the hotspots of high-fidelity simulations of FOWTs to novel researchers, as well as to provide some suggested solutions.

Cost-Effectiveness in Testing and Simulation Balancing the need for accuracy with budget constraints is a challenge many engineers face. Our latest webinar highlighted the cost-saving benefits of combining Computational Aeroacoustics (CAA) with traditional wind tunnel testing. While wind tunnel tests are essential, they can be expensive. By optimizing the data collection process and integrating CAA, engineers can extract maximum information with fewer tests, reducing costs without sacrificing precision. Are you interested in learning how to make your simulations more cost-effective? The webinar recording is available now!
