Computational Fluid Dynamics (CFD) Based Studies

Effectively managing the risks posed by fires, explosions, gas dispersion, and other hazardous phenomena requires more than basic engineering judgment—it demands a detailed understanding of how these events behave in real-world conditions.

Computational Fluid Dynamics (CFD) is a powerful simulation tool that enables this level of insight, providing high-fidelity modelling of complex physical processes within industrial environments.

What are CFD-Based Studies?

CFD studies utilize advanced numerical methods to simulate the behaviour of fluids and gases—along with associated heat transfer, chemical reactions, and pressure waves—under dynamic and often hazardous conditions. These simulations allow engineers to predict the impact of events such as toxic gas releases, jet fires, fireballs, confined explosions, or dust deflagrations with high spatial and temporal resolution.

CFD is especially valuable for assessing how these hazardous events interact with facility geometry, ventilation patterns, containment features, and mitigation systems. The results support informed decisions throughout the design, operational, and emergency planning phases of a facility’s lifecycle.

Our CFD Approach

Our approach to CFD-based studies combines industry-leading software tools with deep domain expertise in process safety and fluid dynamics. A key tool in our arsenal is FLACS, a specialized CFD software widely recognized in the oil & gas and process industries for its accuracy in modelling hazardous scenarios.

We tailor each study to the unique characteristics of the facility or system under evaluation. Our key capabilities include:

  • Gas Dispersion Modelling :

    Using FLACS-Dispersion, we simulate the movement and accumulation of flammable or toxic gases under varying atmospheric, confinement, and ventilation conditions, accounting for complex terrain and obstructions. And analyze desired threshold concentration plume and its impact on sensitive receptor areas.

  • Fire Simulation:

    FLACS-FIRE helps in analysis of jet fires, pool fires, and fire plumes, including flame geometry, heat flux, and thermal radiation exposure to surrounding assets and personnel.

  • Explosion Modelling:

    FLACS-GasEx enables detailed prediction of overpressure effects resulting from confined or unconfined vapor cloud explosions, with mapping of impulse loads across critical structures and evaluation of venting effectiveness.

  • Dust Explosion Analysis:

    FLACS-DustEx helps assessment of combustible dust behaviour in enclosed process areas, including deflagration and secondary explosion risk.

  • Venting and Mitigation Evaluation:

    Performance assessment of explosion relief panels, fire barriers, water deluge systems, and other mitigation strategies under simulated hazard conditions.

These studies validate design assumptions, optimize layout and protection strategies, and enhance emergency preparedness.
