Significant improvements are underway for the HYBRID software, a powerful tool developed to simulate particle-fluid interactions. Experts from Research Software Engineering (RSE) at the University of Sheffield will modernize the build system of HYBIRD.
These upgrades aim to address performance limitations and introduce GPU parallelization, enabling faster simulations and the handling of larger-scale experiments. By reducing the computational overhead, HYBRID will become more accessible to new users, lowering the technical barriers and accelerating research progress in the field of fluid-structure interactions.
At the heart of our research lies an innovative approach to simulating submarine cable behavior using the centrifuge at Delft University of Technology. In our envisioned scheme, the cable is represented by a cylinder attached to a rigid frame. To accurately mimic the dynamic interactions, the cylinder is allowed to move through a system of carefully calibrated springs. This setup enables us to closely study and validate the effects of submarine landslides on energy transportation cables, providing crucial insights for the advancement of our project.
This image represents a 2D numerical simulation of a submarine cable impacted by a landslide, conducted using the Discrete Element Method (DEM). In the simulation, the cable is modeled as a movable cylinder, depicted by the large red circle in the center. By allowing the cylinder to move, we can analyze the forces acting upon it as well as the velocity of the surrounding particles, represented by the smaller blue spheres. This detailed simulation is crucial for understanding the dynamic interactions during a landslide event, contributing to the validation of our research findings.
As part of our ongoing collaboration, a team from our project visited the Faculty of Civil Engineering and Geosciences at Delft University of Technology. This visit focused on exploring their advanced laboratory facilities, with particular attention given to the centrifuge. The centrifuge will play a critical role in validating our studies on the interaction between submarine landslides and cables for energy transportation. This hands-on experience and knowledge exchange mark a significant step forward in our research partnership.
At the core of this initiative lies a partnership between The University of Sheffield and TU Delft in the Netherlands. Solidifying this collaboration, Dr. Cabrera recently conducted a research visit, during which he shared his expertise and exchanged ideas with the local team. As a key component of this inaugural visit, Dr. Cabrera delivered a departmental seminar titled "Grains at Play: Does the grain size distribution matter in soil resistance?".
