Computational Fluid Dynamics (CFD) Modelling

Computational Fluid Dynamics (CFD) modelling provides a high-fidelity, physics-based approach for simulating flammable and toxic gas dispersion, explosion overpressures, ventilation effects, and thermal radiation in complex industrial environments. Using advanced tools such as FLACS and in:Flux, we help clients assess hazardous scenarios, optimise designs, demonstrate regulatory compliance, and strengthen safety cases.

Service information

  • Model flammable and toxic gas dispersion in complex geometries and terrains using validated CFD tools like FLACS and in:Flux
  • Calculate overpressure and impulse effects from confined, partially confined, or congested area explosions
  • Evaluate potential for domino effects within and external to sites
  • Evaluate the effectiveness of mitigation measures such as ventilation, barriers, gas detection (e.g. using scenario-based mapping), or layout modifications
  • Apply findings to support facility siting studies, occupied building risk assessments (per API RP 752/753), and emergency response planning
  • Conduct exceedance analyses, sensitivity studies, and probabilistic assessments to quantify hazard exceedance probabilities (e.g. design accident loads)
  • Integrate CFD results with Quantitative Risk Assessment (QRA), fire and gas mapping, consequence modelling, and COMAH Safety Reports
  • Produce clear visual outputs overpressure contours, gas concentration plots, and ventilation flow paths
