Simulation of Thermal Infrared Images from Simulated Fire Scenes

Journal of Physics Conference Series (2024)

Ronan Paugam Hadi Bordbar Alba Àgueda Omar Regaieg Eric Chavanon

Abstract We summarize here the current development of a simulation strategy aiming at creating a 3D virtual fire lab that can model radiative transfer in simulated fire scenes, and render images in the infrared spectrum. While the end objective is to simulate open landscape scale vegetation fires to help improving fire monitoring Earth Observation products, this work presents a validation exercise performed using a small scale fire scene focusing on flame emission. The fire scene is simulated using the Fire Dynamics Simulator (FDS) model to generate 3D distribution of temperature, soot volume fraction, and CO 2 , CO and H 2 O gases molar fractions. It is then passed to the 3D Discrete Anisotropic Radiative Transfer (DART) model to simulate radiative transfer in multiple infrared bands at a spectral resolution of 0.25 μ m, and render images or intensity spectrum in the infra red spectra that can be compared against direct measurements.

Estimation of 3D Shape and Volume of Fire Plumes from Multiple Views

Journal of Physics Conference Series (2024)

J.A. Blanco Montse Pardàs Josep R. Casas Ronan Paugam Alba Àgueda

Abstract This study evaluates deep-learning and Shape from Silhouette (SfS) methods for 3D reconstruction of smoke plumes. It demonstrates the deep-learning method’s superiority in cases with limited camera views and calibration data, achieving high-quality reconstructions of semi-transparent smoke without precise calibration. The research emphasizes the significance of pre-processing and data appearance for neural network efficacy. By improving 3D reconstruction techniques, this work aids in advancing wildfire tracking and environmental analysis, offering a practical approach for real-world applications in fire science.

Fires at the wildland-industrial interface. Is there an emerging problem?

Fire Safety Journal (2023)

Eulàlia Planas Ronan Paugam Alba Àgueda Pascale Vacca Elsa Pastor

Over the past years, wildfires have raged with unprecedented intensity across the world, becoming a growing problem, as weather conditions conductive to wildfire ignition and spread will increase in frequency and severity worldwide. This, coupled with a growing human expansion, leads to an increase in wildfire risk and in the threat to wildland-urban interface (WUI) communities. Commonly, definitions for WUI areas consider homes, commercial facilities, office and public buildings. This excludes industrial installations, where wildfires can trigger accidents or cascading events leading to extremely dangerous situations for the population causing enormous economic losses. In this paper, the problem associated to the wildland-industrial interface (WII) is analyzed. A methodology to obtain a global WII map is described, and the first WII maps for Europe and Asia are provided. Results show that, in Europe, 2.5% of the land and 6% of vegetated areas are WII, while in Asia these are respectively 0.24% and 0.5%. An analysis of how wildfire triggered industrial accidents can be considered when performing quantitative risk assessments (QRA) in industrial sites is also performed, identifying the current state of the art and research gaps, with the aim of helping industry, public authorities and policy makers, for better accident prevention, preparedness and response.
