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

Paper Publication: We are thrilled to announce the publication of our latest paper, “Assessment of CO₂ Storage Capacities and Identification of Operational Risks Using Large Basin-Scale Multi-Physics Simulation on Unstructured Mesh,” presented at ADIPEC Exhibition and Conference #ADIPEC2024. In this study, we explore the critical aspects of CO₂ storage, focusing on safe and permanent storage solutions that align with global decarbonization goals. Our research utilizes advanced multiphysics simulations (GEOS) on unstructured grids to assess storage capacities and operational risks over large areas and extended periods.

🚀 Exciting advancements in carbon sequestration research! 🚀 Understanding how CO2 mineralisation affects the porosity, permeability, and pore network of host rocks is vital for evaluating basalt reservoirs as potential CO2 repositories. We are thrilled to share our latest manuscript documenting our innovative x-ray translucent environmental cell that allows real-time, grain-scale study of carbon mineralisation and fluid-rock reactions under simulated geological conditions. Key features include: 🔹 Autonomous operation from CT instruments 🔹 Long-duration operando experiments with periodic quenching and scanning 🔹 Controlled conditions of chemistry, temperature (up to 200 °C), and fluid pressure 🔹 Digital image analysis to track porosity and permeability changes 🔹 Full sample recovery for post-mortem analyses Our cell is made from readily available materials and can be reproduced at low cost with standard workshop equipment. This development opens new doors for understanding and improving carbon sequestration methods. 🌍💡 You can read the Open Access paper for free here: https://lnkd.in/eyGi7kHy #CarbonSequestration #CO2Storage #GeologicalResearch #Innovation #Sustainability

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

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.

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

🚀 New Research Alert! 🌊 I’m thrilled to share my latest article published in Water Journal by @MDPIOpenAccess, where we explore the application of Smoothed Particle Hydrodynamics (SPH) using the DualSPHysics _ code for simulating and controlling 3D fluid flow—specifically focusing on sluice gates and weirs. 🔗 Check out the full article here: https://lnkd.in/dnBYY_ky #SPH #DualSPHysics #3DFlowControl #FluidDynamics #WaterResources #Hydrodynamics #Simulation #ComputationalFluidDynamics #Research  @MDPIOpenAccess 

Digital Rock Physics (DRP) is redefining how we study and interpret the properties of subsurface geological formations. By integrating imaging technologies like micro-CT scanning with computational simulations, DRP enables detailed exploration of a rock’s internal structure and behavior. This innovative method is crucial for applications in groundwater management, geothermal energy, carbon storage, hydrogen subsurface storage, and hydrocarbon reservoirs. The DRP workflow starts with high-resolution imaging of rock samples using tools such as micro-CT or FIB-SEM. These images undergo processing to eliminate noise and artifacts, followed by segmentation to distinguish features like pore spaces, rock grains, and pore fluids. Advanced modeling techniques, including pore-scale simulations (either direct numerical simulation or pore network modeling), are then applied to assess rock properties and flow dynamics. p.s. The video was created by GeoDict (Math2Market GmbH), showing a limestone rock sample and its flow field was calculated by solving the Navier Stokes equation. #DigitalRockPhysics #Geoscience #SustainableSolutions #SubsurfaceAnalysis #Groundwatermanagement, #Geothermal #Energy, #CarbonStorage

🎉 Excited to Share My First Research Publication! 🚀 All praise and thanks to Allah, the Almighty, for His guidance and blessings that made this achievement possible. I'm thrilled to announce that my first article as the second author has been published! 🎉 The paper, titled "Non-intrusive experiments on coupled bubble dynamics and heat transfer during nucleate boiling under varying pressure conditions," is now out in the Applied Thermal Engineering journal, a top-tier UK-based journal with an impact factor of 6.1 and an H-index of 206. This wouldn’t have been possible without the incredible support and guidance of my supervisor, Prof. Atul Srivastava, and my amazing senior, Alok Kumar (first author). Huge thanks to both of you for all the mentorship and collaboration—it’s been an absolute honor working with you! The research focuses on understanding bubble dynamics and heat transfer during nucleate boiling using non-intrusive methods. It was an exciting and challenging journey, and I’m so glad to see it come to life in such a prestigious journal.
