The new peer-reviewed journal article, Experimental Investigation of Explosion Hazard from Lithium-Ion Battery Thermal Runaway has been published in FUEL. Authored by collaborators from FSRI and UL Solutions, this paper investigates the explosion hazards of lithium-ion battery thermal runaway gas. The paper summarizes a series of experiments conducted in an enclosed garage structure using modern North American construction design. The relationship between battery size and potential explosion severity is established following data analysis.

For my fellow fire nerds, this is a fantastic read on the effects of a simulated EV offgasing and ignition in a garage, with structural analysis and overpressure data measurements by FSRI. The paper itself is a long and fascinating read citing recent losses and the associated test methodology to support the analysis. They tested both NCA and LFP cells, though the garage was empty (faster flame wave), to do the testing. Almost the exact scenario in the photo below happened in real life in Colorado. Some basic info about this paper itself, the Colorado incident, and other issues can be found on the reference I have at the end of this sentence, if your reading time is limited to 3:44: (https://lnkd.in/gQPgTfkj)

Pierrick Cordel, Alexandre Dély, Adrien Merlini, Francesco P. Andriulli introduce new integral formulations based on the convolution quadrature method for the time-domain modeling of perfectly electrically conducting scatterers that overcome some of the most critical issues of the standard schemes based on the electric field integral equation (EFIE). The standard time-domain EFIE-based approaches typically yield matrices that become increasingly ill-conditioned as the time-step or the mesh discretization density increase and suffer from the well-known DC instability. This work presents solutions to these issues that are based both on new Calderón strategies and quasi-Helmholtz projectors regularizations.

Today, Jesper Karlsson and I have submitted our final thesis, marking the end of our journey as Bachelor students at Jönköping University and our transformation into Architectural Engineers. Our project, titled "Enhancing Building Energy Performance: A Comprehensive Analysis Through Energy Simulation Tools," involved using Grasshopper, Honeybee, and Ladybug to conduct various energy simulations. These tools helped us determine the building's enhanced energy class. The following video, created by me and narrated by Jesper Karlsson, summarizes the entire process.

I am happy to share that our latest research paper: "Underwater noise from vibratory pile driving with non-linear frictional pile–soil interaction" has been published in the Journal of Sound and Vibrations! Vibratory piling technologies are promising in reducing underwater noise in offshore monopile installations. Most piles are still driven by hammer impact on top of the pile, causing pressure waves in the water column and disturbing marine life. Consequently, noise prediction models are tailored to this technology. Contrary to impact piling, vibratory pile driving is continuous, introducing other modelling challenges. In this paper, we studied noise emission in vibratory pile driving, emphasising the pile-soil interaction, which is essential to accurately describe the noise generation in vibratory piling. The paper's main findings are that: -- The primary source of noise generation is the radial vibrations of the pile. -- The system is prone to resonances close to the in-vacuo natural frequencies of the pile when the pile and soil are loosely coupled, resulting in significant radial pile vibrations. -- The superharmonics of the primary driving frequency, generated by the hammer, heavily influences noise predictions during vibro-driving. -- The Coulomb friction responds mainly to the driving frequency and shifts energy to higher harmonics. Depending on the phase, this can either excite or dampen the pile vibrations. -- The noise field is found to be highly sensitive to the change in the system dynamics during penetration of both small and large monopiles.
