This simulation shows how wind flows over the blades of a wind turbine. The surrounding environment is displayed in a mesh environment to depict how the landscape interacts with the environment and whether there are any interferences. CFD also helps to depict the stresses that are applied to the design and whether it can have effects on the performance.

"Engineering Branches" series, post 25/26 Fluid Mechanics. The study of how fluids (liquids and gases) behave and interact with their environment, with applications ranging from aerodynamics to oceanography. Challenge: Understanding fluid behavior and developing technologies to improve efficiency and reduce environmental impact in areas such as transportation, renewable energy, and water management. Significant achievement: Advancements in wind turbine blade design using Computational Fluid Dynamics (CFD) have drastically improved the efficiency of renewable energy production, making wind power a more viable alternative to fossil fuels. Interesting fact: The Reynolds number, a dimensionless quantity that characterizes fluid flow, is named after Osborne Reynolds, a British engineer who studied fluid mechanics in the late 19th century.

💡 #Highcitedpaper #Korea Maritime & Ocean University 🌊 Title: CFD Simulations of the Effect of Equalizing Duct Configurations on Cavitating Flow around a Propeller 🔑 Keywords: computational #fluiddynamics (#CFD); #energy saving equalizing duct; #cavitation; #marine #propeller; #OpenFOAM 🔗 See more: https://lnkd.in/gYARXJmy 📜 Abstract：This study presented the results of a computational study of cavitating flows of a marine propeller with energy saving equalizing ducts. The main purpose of the study was to estimate the cavitating flows around a propeller with a duct, and to investigate the interaction between a duct and a propeller in cavitating flows. The INSEAN E779A propeller was used as a baseline model. Validation studies were conducted for non-cavitating and cavitating flows around a hydrofoil and a propeller. A comparison with the experimental data showed good agreement in terms of sheet cavity patterns and propulsion performances of the propeller. Various duct configurations have been presented, and it was found that a duct in front of the propeller had effects on the propeller’s cavitation and propulsion performance. Higher angles of attack of the duct showed a significant effect on the propeller’s cavitation behavior, especially with a small duct. The small duct lowered the cavitation inception radius with increase in angle of attack of the duct, while the large duct had more effect on the tip cavitation. The propeller with large duct gave higher thrust, however, the higher torque loading affected the propeller efficiency. Overall, it was found that the propeller with small duct provided a higher propeller efficiency.

⚡Time Dependent CFD Simulation: Vortex Shedding⚡ What is Vortex shedding?👇 Vortex shedding is a phenomenon, when the wind blows across a structural member, vortices are shed alternately from one side to the other, and where alternating low-pressure zones are generated on the downwind side of the structure giving rise to a fluctuating force. This phenomenon is of major importance in engineering design because the alternate formation and shedding of vortices also creates alternating forces, which occur more frequently as the velocity of the flow increases. 🌎 Source: https://bit.ly/3nRj1Jr 📥 Latest newsletter: https://lnkd.in/d7B7fqA #engineeredmind #science #technology #engineering #mechanicalengineering #physics #mathematics

Stress and deformation analysis of a 5MW NREL Composite Wind Turbine Blade. The Stress forming and deformation in terms of wind load, centrifugal force and gravity force is visible here. Currently me and my team are working on this project to evaluate the performance of the blades. The simulation is done in COMSOL Multiphysics 6.1. The Eigenfrequency vs RPM vs Displacement seemed allowable. Hopefully we will find something interesting enough to present. #MechanicalEngineering #Simulation #Comsol #StressAnalysis #research #windturbineblade

⚡ Wind is NOT a Steady Thing - From RANS to LES ⚡ CFD-steady solutions deliver mean properties, such as mean velocity and mean pressure. Even though they have many engineering applications, wind pressures manifest high-frequency peaks that steady or low-resolution simulations cannot predict. Besides, low-fidelity simulations fail to indicate susceptibility to resonance and other turbulence phenomena that affect structures. Experienced wind engineers use high-fidelity large eddy simulations (LES) to compose wind loads for structural projects. 🌎 Source: AeroSim #engineeredmind #engineering #simulation #cfd #les #rans
