Leaks and explosions
CFD analysis enables modeling of leak, fire, and explosion scenarios during the design phase, enabling efficient safety planning and risk minimization.
Preventing leaks, fires, and explosions by CFD modeling is an important part of process design and risk analysis. These analyses are widely used for modeling the consequences of various accidents. They are also important input data for designing different machinery and equipment, and for ensuring structural integrity.
Consequence modeling for accidents is often related to the handling of hazardous chemicals and gases. By modeling potential accident scenarios, it is possible to determine in advance the impacts of accident situations on the surrounding area. Identified and observed risks also help reduce the probability of accidents.
In explosion simulation, the pressure and thermal radiation effects caused by an explosion are applied to surrounding structures. The examination may focus on, for example, structural integrity and the protection provided by the structure. Explosion analyses can range from blast analyses of individual explosives to vapor cloud explosion analyses.
Accident simulation: hydrogen release and explosion in 1980s Stockholm
CFD modeling is used to estimate the released hydrogen mass, the size of the resulting gas cloud, and the fraction of flammable gas. Based on these results, the explosion magnitude and resulting damage can be assessed, enabling more accurate predictions and improved risk management.

In hydrogen projects, safety planning is taken into account right from the very first stages of design. Designing for safety requires a diverse understanding of chemical and physical processes.
Finding the full potential of CFD
CFD, or Computational Fluid Dynamics, is a method that is often utilized only for the post-design phase, although it is very well suited for wider and efficient use throughout the design process. Optimal use of CFD analysis generally shortens projects’ lead times and improves product assessment. It also provides an excellent basis for preparing digital twins. In process modeling tasks, CFD is an excellent tool for studying the components, for example.
Not only colorful pictures – CFD saves time and money
Did you know that by using computational fluid dynamics (CFD) you can save as much as 80 % in design time and 60 % in design costs? During the past 20 years, I’ve been lucky enough to participate in many interesting simulation projects both in Finland and abroad and have seen how clients have received instant help. But what is CFD really? Where can it be applied and why should it be utilized?
