Fire and smoke gas simulation
Advanced Fire Simulation Services at Gruner
In the event of a fire, accurate and timely assessment of smoke gas propagation and temperature distribution is crucial for ensuring safety and mitigating damage. At Gruner, we leverage state-of-the-art computer-based fire simulations to virtually investigate fire events. This advanced approach enables us to provide detailed insights and solutions for fire safety in various environments, ensuring the highest standards of safety and reliability.
Our fire simulations utilize sophisticated Computational Fluid Dynamics (CFD) models, including the Fire Dynamics Simulator (FDS) and STAR-CCM+ from CD-adapco. These tools are at the forefront of fluid mechanics and thermodynamics simulation, allowing us to analyze the behavior of fires with unparalleled precision.
Fire Dynamics Simulator (FDS)
FDS is a highly specialized CFD tool developed specifically for fire simulations. It uses a large-eddy simulation (LES) technique to model the turbulent flow of smoke and hot gases produced by fires. By incorporating detailed chemical reactions, heat transfer, and combustion models, FDS can predict the spread of fire, smoke movement, and temperature changes within buildings. This makes it an invaluable tool for designing and assessing fire safety measures in various structures, from residential buildings to large industrial complexes.
STAR-CCM+
STAR-CCM+ is a comprehensive CFD software suite designed to handle all aspects of fluid flow and heat transfer. While not exclusively a fire simulation tool, its versatility allows it to address complex fire scenarios, including those involving intricate room geometries and multiple interacting systems. STAR-CCM+ can simulate the behavior of smoke and hot gases in detailed 3D models of buildings, providing insights into the performance of ventilation systems, the effectiveness of fire barriers, and the impact of different fire safety strategies.
