🔟 Fuel Cell Validation: Case Study 🔋
In the tenth position of our TOP 10, we present not just one post, but a series of 3 interconnected posts, exploring the validation of fuel cells through advanced simulation analysis.
Opening the series, we detail multiphysics modeling and CFD (Computational Fluid Dynamics) simulation with Simcenter STAR-CCM+. This post presents a digital reproduction of the JRC ZERO∇CELL fuel cell, validated against real-world testing, and explores how to integrate fluid flow, heat transfer, chemical and electrochemical reactions.
In the second post, we focused on structural analysis (FEA), using Simcenter 3D and Solid Edge. The robustness of the cell was validated considering pressure and temperature conditions imported from Simcenter STAR-CCM+, with emphasis on the fatigue analysis and mechanical resistance of the system.
Closing the series, this post addresses systemic simulation in Simcenter Amesim, exploring the integration of fuel cells into vehicle systems. The analysis highlighted the dynamic performance, energy efficiency, and scalability of the solution in hybrid and electric vehicles.
Studying the impact of deformation of flexible components on NVH (Noise, Vibration and Harshness) has always been a challenge. With Simcenter 3D Motion and its Modal Editing functionality, engineers can now precisely adjust modal frequencies and optimize the performance of systems such as powertrains. This innovation has already demonstrated significant vibration reductions at speeds up to 4,000 rpm, simplifying processes and delivering superior results.
Gas turbines represent the pinnacle of engineering, combining complex physics and intuitive design. Behind their intricate beauty, advancements like the HEEDS AI Simulation Predictor are transforming the design and optimization process. Recent studies have shown that integrating machine learning into simulation tools like Simcenter STAR-CCM+ and NX has been able to save up to 49% of simulation time and increase component efficiency by up to 10%. These advancements highlight how technology can reduce costs, accelerate projects, and increase market competitiveness.
The E3 UFSC team set a historic milestone at the Shell Eco-marathon Brasil 2024, reaching 381 km/kWh with its electric battery prototype. The achievement was supported by CAEXPERTS and Siemens technologies, which provided cutting-edge tools such as NX, Simcenter STAR-CCM+ and Simcenter 3D. With innovations such as a new transmission system and carbon fiber wheels, the team optimized its design to achieve maximum efficiency, consolidating itself as a reference in sustainable projects and pushing the limits of energy performance.
The accuracy of an engine model depends directly on the quality of the defined boundary conditions. Tools such as Simcenter 3D, Simcenter Amesim and Simcenter STAR-CCM+ allow you to capture critical phenomena such as heat transfer coefficients and thermal fluxes, incorporating proprietary correlations and engineering knowledge. With advanced simulations and integration of 2D and 3D models, it is possible to optimize the performance of gas turbine engines in different operating scenarios, ensuring efficiency, accuracy and longer component life.
