CIDETEC’s Post

Research, teaching and publications are the main tasks of a PhD Student and I will proudly present my 4th publication during the ASME Congress in London this week. Essentially technical, here we compare CO2, CO, NO, NOx, O2 and Smoke Number emissions of a drop-in sustainable aviation fuel (specifically developed by Neste and Virent). The work carried out with and by Jean-Louis Champion's Bearcat teams is enabling us to take our industry to the next level, with the prospect of 100% SAF "Drop-In" within the next few years. This approach is important because most of the aircraft that will be flying in 2050 have already been developed. A "Drop-In" grade is therefore very likely to be the only option for the vast majority of the fleet in 2050. Reminder: a relevant technical solution is never sufficient on its own, and future publications will focus on the societal aspect of decarbonizing aviation. https://lnkd.in/eDGXiu37

🔥 I'm excited to present my work at ASME's Turbo Expo 🚀 in London. Is anyone else attending? 🔥 NUMERICAL INVESTIGATION OF THE COMBUSTION PROCESS IN A LEAN BURN GAS TURBINE FUEL INJECTOR The present work investigates the aerodynamics and combustion characteristics of a novel fuel flexible lean burn fuel injector. Methane and hydrogen are considered as the fuel with different mixing ratios. Flame stability, temperature distribution, and species concentration are assessed to obtain the operational characteristics of the fuel injector. The injector assembly consists of pilot and main mixer blocks and each of them includes a set of axial and radial swirler assemblies. Considering the mixture as partially premixed, steady-state RANS turbulent combustion modelling is performed with standard k-epsilon model and steady diffusion flamelet model. Hydrogen is blended with methane with different mixing ratios ranging from 0-100%. Four geometrical configurations with pilot and main mixer fuel-air combination are considered with representative flow conditions. The pilot and main mixers generate individual recirculation zones and stable flame anchoring is observed for all cases. A uniform and symmetric temperature distribution is observed with Two Temperature peaks corresponding to main and pilot flame fronts. The hardware anchors the flame till 50% hydrogen concentration and any further addition resulted in an unstable flame.

I'm excited to present two research papers at ASME TURBO EXPO 2024 (ASME International Gas Turbine Institute) in London. Is anyone else attending? 😊 My second paper titled: 'GT2024-126107: DESIGN STRATEGY OF THRUST GAS BEARINGS FOR REFRIGERANT COMPRESSORS CONSIDERING EFFECTS OF CENTRIFUGAL FORCE AND CONVECTIVE INERTIA' presents design strategy by consideration of 3D thermo-hydrodynamic (THD) performance of rigid thrust gas bearings lubricated with a refrigerant gas using Reynolds Equation and computational fluid dynamics (CFD). The gas bearing is operated in both hydrodynamic and hybrid modes at high ambient pressures typical to the bearing compartment of refrigerant compressors. The CFD simulations adopted an advanced turbulence model and Peng-Robinson real gas equation of state while the Reynolds Equation-based THD model adopted NIST Refprop for real gas model. Results from the two models are compared, and detailed observations on gas bearing performance are presented including load capacity, pressure profiles, streamlines, effect of convective inertia, centrifugal force and Mach number, etc.

What is the impact of manufacturing and build-to-build variations on the aerodynamic performance and aero-mechanical response of multi-stage axial compressors? What approaches should we use to model them for industrial applications, as part of the design process and to support engine development tests? Next week, at #ASME #TurboExpo2024 I'll answer these questions, and provide some of our experience by sharing some the work we carried out at Siemens Energy, together with my co-authors Senthil Krishnababu CEng, FIMechE, FHEA and Simon Jackson. I'm looking forward to some good discussion with the audience! 💡 GT2024-122636: Manufacturing and Build Variations Modelling for Multi-Stage Axial Compressors: CFD Aerodynamic Predictions 📅 Date: Friday, June 28, 8:00 AM - 10:00 AM 🌐 Link: https://lnkd.in/eF9V3H32 💡 GT2024-125093: Manufacturing and Build Variations Modelling for Multi-Stage Axial Compressors: Forced Response Predictions 📅 Date: Wednesday, June 26, 4:00 PM - 5:30 PM 🌐 Link: https://lnkd.in/eqrJaude This work was also the starting point of a research collaboration with the University of Lincoln, Lincoln AI Lab (LAIL) and Sepehr Maleki , in which we are exploring the use of machine learning to predict the effect of manufacturing and build variations on the compressor aerodynamic performance.

Astonishingly, we fly today in aircraft designed and certified using turbulence measurements made in the 1960s. But the atmosphere has changed since then, containing at least 55% more severe turbulence in places, with further large increases in store. That's why I'm leading a new three-year research project, co-funded by Airbus, to update the 1960s turbulence model and ensure it is still fit for purpose. This work will future-proof aircraft design and certification standards for decades to come. Watch this space for updates from me and my PhD student Joana DeMedeiros on this vital research.

🎉 Congratulations to Sergio Sanz Pérez for successfully defending his Bachelor Thesis, under the supervision of Rauno Cavallaro! 👏 ✈️ In this work, titled "Development of a Mid-Fidelity Platform for Flight Load Assessment (FLAP) in Early Design Phases of an Aircraft", the most critical load cases required by airworthiness regulations are integrated within FLAP. This computational tool allows the user to rapidly simulate the aerodynamic forces acting on an aircraft under various maneuvering conditions by incorporating the mid-fidelity aerodynamic solver DUST. The rapid and accurate simulations of the load cases make FLAP particularly useful during early phases of the aircraft design process in which many iterations are required.

Aviation climate change adaptation is really starting to get more momentum
