While useful, screening-level analyses often don’t provide the high-fidelity modeling required for an in-depth examination of complex hazard scenarios. Analyzing a problem with Computational Fluid Dynamics (CFD) can better predict the consequences of postulated scenarios. In comparison to a screening level analysis, CFD analysis results typically lead to more effective and more cost-efficient mitigation solutions. The experts at BakerRisk leverage their comprehensive experience in research, development, and the application of CFD tools to better simulate event scenarios and provide high-quality solutions.
BakerRisk developed BWTI© (Blast Wave Target Interaction) to simulate the generation and propagation of blast and shock waves and their interaction with structures. BWTI© has been extensively used for designing test enclosures to protect against high-pressure pneumatic failures and high explosives for industrial and government clients. It excels in replicating and modeling blast waves resulting from VCEs, bursting pressure vessels, and high-explosive detonations. Its primary application lies in engineering-level analyses, particularly within scenarios where the nuanced aspects of blast wave shielding and focusing come into play.
The FLACS (Flame Acceleration Simulator) code is an industry-standard CFD tool that our team at BakerRisk utilizes in many projects to model flammable gas and evaporating liquid releases and dispersions, toxic dispersion distances, blast loads due to vapor cloud explosions (VCE), and exhaust heat plumes for both on-shore and off-shore facilities. FLACS is commonly used to analyze typical refining and processing facilities, chemical facilities, and offshore production. In recent years, it has been extended to model hazards associated with all phases of renewable hydrogen (production, storage, transportation, and consumption).
Unique applications of this software include evaluating the efficacy of mitigation strategies, such as vented deflagrations, gas detector layout and response, dispersion barriers, and DDT prevention through modifying congestion configuration.
FDS (Fire Dynamics Simulator) was developed by the National Institute of Standards and Technology within the U.S. Department of Commerce. It’s a sophisticated CFD model designed to simulate heat and smoke transport from fires with a versatile toolset that allows for the computation of various other non-thermal-related low-speed fluid flow simulations.
For example, FDS has been used to effectively model fire spread through buildings, liquid pool fires, mist dispersion, and buoyant mixing calculations to accurately determine hazards at industrial and private facilities. In combination with the Pathfinder program, it is able to determine personnel evacuation efficiency during hazardous fire events. A primary component of the FDS tool is Smokeview, a companion program capable of producing high-quality images and animations, making it an indispensable tool for assessing hazards.
BakerRisk has tested and validated many of the above computer models and technologies within our very own test site. As a result, you can trust our fluid dynamics experts because we don’t just perform modeling: we ensure that computational models work properly before leveraging them in real-world scenarios. We’ve also published major studies and papers relating to this field.
