Congratulations to our PhD student Wei Wang on his first published journal paper (ASCE Publishing). Wei's work is based upon centrifuge cyclic loading of large screw anchors for floating wind under cyclic loading. Importantly it shows the effects of installation on axial performance and how the benefits of overflighting (AR<1) are maintained during cyclic loading. He's also developed some cyclic interaction diagrams and compared with straight shafted piles as well as a predictive framework for displacement accumulation and capacity degradation. Watch out for coming papers using DEM to explain the behaviour from a particle scale perspective. Well done Wei Wang. Thanks for team contribution on DEM (Matteo Oryem Ciantia Yaseen Sharif) and centrifuge testing (Craig Davidson) #screwpiles #cyclicloading #floatingwind #renewableenergy https://lnkd.in/eVA_ZYwS

🌊 Just published: our latest article exploring experimental methodologies for estimating mass transfer characteristics, particularly the Nusselt number, in horizontal cylindrical tanks pressurized with two-phase fluids. By replicating operating conditions that would occur in tanks containing liquid hydrogen for future aircraft, we utilized a circular cross-section tank as a test bed, with water serving as a surrogate fluid. Key findings indicate that in case of intense sloshing the Nusselt number remains constant over time in stationary processes and is independent of the fluid thermodynamic state. This constancy allows for the mapping of the Nusselt number in deterministic harmonic processes with varying amplitudes and frequencies. This research - that served as a proof of concept for Horizon HASTA project - aims to enhance our understanding of mass transfer in cryogenic systems, paving the way for advancements in future aviation technologies. ✈️ https://lnkd.in/d7CuT9EA Marco Pizzoli Mario Tindaro Migliorino Francesco Gambioli Franco Mastroddi Ramon Abarca @Giuliano Coppotelli Tiziano Pagliaroli Fabio Del Duchetto Antonello Binni

Publication alert 📢 🔔 😀 Our latest open-access article 'Investigating supercritical flow characteristics and movement of sediment particles in a narrow channel bend using PTV and video footage' related to sediment bypass tunnel research is now available in the journal 'Advances in Water Resources', Elsevier. Access it via https://lnkd.in/dajyJ2bc This novel experimental investigation advances the knowledge of turbulence characteristics, secondary currents, and sediment movement under supercritical flows in narrow channel bends and identifies the cause of nonuniform invert abrasion at sediment bypass tunnel bends - very useful in the design of these hydraulic structures that are used in mitigating reservoir sedimentation. It also produces experimental data to validate future numerical models dealing with the hydrodynamics of supercritical bend flows. The research was carried out through a successful cooperation among Norwegian University of Science and Technology (NTNU), Luleå University of Technology, Vattenfall AB, Technical University of Munich, ETH Zürich, and HydroCen (Norwegian Research Centre for Hydropower Technology) with great contributions from my supervisors and co-authors, Dr. Sofia Larsson, Dr. Mats Billstein, Prof. Nils Rüther, Prof. Leif Lia, and Dr. Elena Pummer. Many thanks to Mr. Pär Nilsen for constructing such a tricky physical model and to Dr. ismail A. and Prof. James Yang for contributions in planning the research. #PhD #CivilEngineering #HydraulicEngineering #Fluidmechanics #OpenChannelFlow #ChannelBend #NarrowChannel #SecondaryCurrents #SupercriticalFlow #Experiments #PTV #Lavision #SedimentTransport #SedimentBypassTunnel #HydroAbrasion #ReservoirSedimentation

I had the privilege of presenting our research on Thermo-Hydro-Mechanical and Gas Transport (THM-G) Modelling of the Gas Permeable Seal Test (GAST) at the Clay Conference 2024 in Hannover. As part of the UPC and CIMNE team, alongside Prof. Sebastia Olivella and Prof. Enrique Romero, we developed a comprehensive numerical simulation of a decade-long in-situ water and gas injection test conducted at the Grimsel Test Site (GTS) in Switzerland. Laboratory-scale tests, including oedometer tests performed at UPC, were integral to the model calibration process. Our modeling and test interpretation highlight the effective functioning of sand-bentonite mixtures (80/20) as gas permeable seal in the context of "engineered gas transport system" (EGTS). While ongoing investigations continue to explore the long-term behavior of gas within deep geological repositories, our findings suggest that engineered gas transport systems could offer a viable solution based on the GAST results. This research was funded by NAGRA, the organization responsible for the development of Switzerland’s final deep geological repository (DGR). Our results, along with the interpretation of test data, were incorporated into NAGRA’s recent general license application for the final repository in Switzerland. #ClayConference2024 #DGRdesign#NuclearWasteManagement #GeotechnicalEngineering #THMGModelling

Our book chapter on the experimental and modelling investigations of hydrogen subsurface storage is out. I'm glad having contributed to such a book alongside my colleague Mohamed Rezk, Ph.D.

Happy to share our latest study just published in Geoenergy Science and Engineering  entitled “Comparison of geomechanical upscaling methods for prediction of elastic modulus of heterogeneous media” by Farshad Sadeghpour, Ardavan Darkhal, Yifei Gao, Hem Motra, Ghasem Aghli, Mehdi Ostadhassan.  The aim of this paper is to estimate Young's modulus of a shale sample from several major upscaling mathematical methods and compare the results to polyaxial compressive strength test and nanoindentation measurements on the same piece of sample. To achieve this, five major theoretical upscaling models, including Differential effective medium (DEM) method, Mori-Tanaka (MT) method, Self-consistent approximations (SCA) method, Kuster and Toksӧz Formulation (KTF) method, and Dilute model (DM), have been utilized to calculate the Young's modulus based on constituent components of the sample that was obtained from routine XRD and geochemical analysis. The calculations for each of the five methods were performed in two scenarios: without incorporating the organic matter in the model and with it, in a range of porosity values while input parameters for each constituent component were found from the literature. Furthermore, the use of upscaling methods reduces the need for destructive testing and also eliminates the requirement for expensive equipment with limited access to proper size of the samples and required preparations that should be followed.

Glad to share our another recent paper in International Journal of Greenhouse Gas Control: "Robust CO2 Plume Imaging by Joint Tomographic Inversion using Distributed Pressure and Temperature Measurements". It extends the streamline-based inversion algorithm to incorporate DTS data and thermal process. And then proposes a hierarchical history matching workflow combining multi-objective Genetic Algorithm (MOGA) and streamline-based inversion. The proposed workflow is applied to Chester-16 CO2 injection field to better monitor CO2 propagation with the integration of distributed pressure and temperature (DTS) measurements.
