#throwbackthursday | Shape Optimization of a Tidal Stream Turbine The world’s first large-scale tidal energy farm at 8 MW was developed by SIREHNA, a subsidiary of DCNS in France. To design the most efficient tidal stream turbine, Sirehna elected to use CAESES for creating the variable geometry model with 19 design variables. In total, about 700 designs were simulated using the commercial CFD code STAR-CCM+ by Siemens Digital Industries Software and an automated optimization was performed. According to Pol Muller, Head of Thrusters, “Using CAESES for creating parametric models was MUCH faster and easier than with our traditional CAD tool. With CAESES we can now create all of the design candidates in hours instead of weeks!” https://lnkd.in/grJRhVxE #renewableenergy #turbine #tidalenergy #greenenergy #cfd #optimisation #cad #cae

Building a solenoid engine was a fascinating learning experience. The project involved designing and assembling solenoid to drive a piston, replicating the motion of a traditional engine using electromagnetic forces. Crafting the coils, ensuring precise electrical control, and managing heat dissipation were challenging but rewarding. Although the engine’s efficiency was low and it struggled with continuous operation due to heat, the process deepened my understanding of electromagnetism and mechanical systems. Despite the limitations, it was an exciting hands-on exploration of converting electrical energy into mechanical motion through solenoids. It enhanced both my problem-solving and technical skills. #solenoids #scienceproject #projects #engineering

Aerodynamic Characteristics Evaluation of S-Series Airfoils https://lnkd.in/dTVS8GAK Abstract The present study utilizes the commercial software ANSYS-Fluent to explore the influence of the geometry of thick S- S-series airfoil on the near-wake region. Four different S-series airfoils, namely S809, S811, S814, and S818, were investigated at a wide range of angles of attack, which were varied from 0 degrees to 20 degrees with an increment of 2 degrees and at a Reynolds number based on chord length Re = 1x106. Analysis of the resultant data revealed that the aerodynamic performance of the S811 and S818 airfoils superseded that of the S809 and S814 airfoils. To illustrate, at the critical angle of attack, S811 and S818 were observed to possess the maximum lift and minimum drag coefficients. Furthermore, in the range of attack angles between 10 and 16 degrees, these airfoils consistently demonstrated lower drag than the others tested, enhancing overall aerodynamic performance. These findings underscore the significant role played by airfoil geometry in influencing aerodynamic performance and provide insights into optimal design parameters for wind turbine blades, particularly highlighting the advantages of the S811 and S818 airfoil shapes. In addition, the effect of the unsteady structures in the near-wake zone behind the trailing was also evaluated through turbulence kinetic energy contours. The results revealed a decrease in turbulence kinetic energy when the S811 and S818 airfoils were placed in a cross-flow compared to the S809 and S814 airfoils. This indicates that the strength of the vortex shedding of these airfoils is lower than that of the S809 and S8014 airfoils. Highlights: - Ansys-Fluent predicts flow around thick airfoils wall at low/mid angles. High angles: lift, drag, near-wake - The airfoil shape significantly shapes the airfoil and wake region flow - S818, S811 airfoils performed best in crossflow while S809, S814 showed poor aerodynamics, especially at high angles Keywords: - Thick airfoil S - series airfoils Horizontal axis wind turbine CFD Wind turbine Journal: https://lnkd.in/dgnvtdte Issue: https://lnkd.in/dZ9drsCM Article: https://lnkd.in/dYQRxWTJ ETJ LinkedIn: https://lnkd.in/d_8SPqAt #Engineering_and_Technology_Journal #UOT #engineering #technology #etj

Simulation Friday - Shipbuilding, offshore energy, and other sectors in marine engineering stand to benefit from CONVERGE, whose specialized features are ideal for analyzing and optimizing designs to improve performance and comply with government regulations. Our software can help reduce design costs and timelines through virtual prototyping, which enables engineers to test multiple designs. CONVERGE’s fluid-structure interaction (FSI) modeling, various multi-phase modeling options, and autonomous meshing can capture the complex physics associated with offshore applications. In addition, the detailed chemistry solver and suite of chemistry tools allow engineers to study fuel behavior, helping to tackle some of the challenges of implementing alternative fuels. In this #SimulationFriday video, we show the installation of a capping stack on a leaking blowout preventer. We used CONVERGE’s species-based volume of fluid solver, rigid-body FSI modeling, and Adaptive Mesh Refinement to accurately capture the capping stack as it is moved to temporarily block the flow of hydrocarbons from the blowout preventer.

Delighted to publish our latest paper in the ASME (The American Society of Mechanical Engineers) with my co-authors Aengus Connolly and Sean Leen recently from the OMAE2024 conference proceedings. It is available here: https://lnkd.in/e5s5eH6q This paper describes the numerical modelling of a novel floating offshore wind turbine (FOWT), a next-generation concept which aims to combine the best features of traditional spar and semi-submersible platforms, coupled with a modular design for ease of manufacturing and assembly. The study was conducted as part of Phase IV of OC6 (Offshore Code Comparison Collaboration, Continued, with Correlation and unCertainty), an international research project focused on verifying and validating numerical modelling tools used in the analysis of floating offshore wind systems. In this study, numerical modelling is performed using a mid-fidelity tool which performs fully coupled aero-hydro-servo-elastic simulations in the time domain. The simulation model is based on a full-scale demonstrator version of the FOWT concept hosting a 3.6 MW turbine, which has been deployed offshore and is fully operational since 2021. Results from the numerical model are validated by comparisons with experimental data from a 1:43 Froude-scale test performed in the University of Maine’s Ocean Engineering Laboratory. Beginning with fundamental test cases, including static equilibrium, surge offsets, and free-decay simulations, the scenarios advance in complexity to include wind-only loads, wave-only forces, and a combination of wind and wave conditions. Key parameters of interest include aerodynamic forces, motions of the floating support structure, tower base moments, mooring line tensions, and keel line tensions. Overall, the results show a strong correlation with the empirical data. This paper complements the research work undertaken in OC6 Phase IV, further substantiating its insights into the dynamic responses of floating offshore wind turbines. #Flexcom #FOWT #WindResearch #OC6 #RenewableEnergy #Wood
