Fire, Smoke Explosion and Egress Simulation Modelling

CFD Computational Fluid Dynamics for Fire, Smoke Explosion and Egress Simulation


Hegel Engineering Sdn Bhd is a leading provider of Computational Fluid Dynamics (CFD) services that offers unparalleled engineering solutions to our clients in the Commercial, Residential, Industrial, Oil & Gas, and Marine industries. Our team of experienced engineers utilizes CFD extensively to simulate Major Accident Hazards, such as jet and pool fires, and provide valuable insights into the nature of complex fluid flows.

Using advanced meshing algorithms, our CFD simulations subdivide the environment into millions of small control volumes, solving the governing equations for mass, momentum, and energy iteratively. As no assumptions are made a priori regarding fluid flow, our CFD simulations offer potentially infinite modelling scenarios, providing an extraordinarily versatile and valuable engineering tool for our clients.

At Hegel, we understand the importance of CFD simulations in identifying and mitigating risks posed by Major Accident Hazards. Our CFD simulations provide critical insights into flow features that are not available from more simplistic phenomenological models. For example, our simulations can illustrate the interaction of a flame with a platform structure or the complex nature of smoke dispersion leeward of an offshore platform. Such insights provide valuable information for our clients to understand the nature of their particular scenarios and develop effective risk management strategies.

In addition to our expertise in CFD, we also offer a comprehensive range of engineering services, including hazard identification studies, fire and gas mapping, and risk assessments. We are committed to delivering reliable and efficient engineering solutions that meet the unique needs of our clients.

At Hegel Engineering Sdn Bhd, we pride ourselves on our commitment to excellence, integrity, and innovation. Contact us today to discuss how our CFD services can help you identify and mitigate risks posed by Major Accident Hazards within your industry.

Fire Modelling using CFD


We understand the importance of ensuring safety and reducing hazards in industrial settings. One of the key areas we specialize in is fire modelling, a critical aspect of risk assessment for various industries. Our fire modelling capability includes jet and pool fire releases for multiple sizes and locations.

We use a specialized combustion model to incorporate the combustion of a jet or pool release into a CFD model. Our team considers both the flame front and the dispersion of combustion products to provide a comprehensive simulation set. The simulation set can include variations in hole/pool size, release location and direction, flow rate, blow-down systems, and atmospheric conditions (such as wind direction and speed).

Our team also incorporates blow-down systems and failure scenarios (jet fires) through pseudo-transient and fully-transient simulations, ensuring we capture all possible scenarios. In addition, we assess the impact of wind direction and speed on the fire, giving our clients a complete picture of the situation.

The results from our CFD simulations provide essential information for significant accident hazard evaluation. In addition, our fire modelling simulations assess the effectiveness of proposed mitigation strategies, helping our clients make informed decisions. Key outputs from our fire modelling simulations include flame front, showing interactions with primary structures, temperature contours, thermal radiation flux contours, and movies of flame development and regression due to the deployment of blow-down systems.

We are committed to providing our clients with the most comprehensive and accurate fire modelling simulations. Our team of experts is highly experienced in the field, and we use the latest technology to provide our clients with the best service possible. With our fire modelling capability, you can rest assured that your industrial setting is safe and secure.

Smoke Modelling using CFD


We understand the importance of safety regarding accidental fire events. Furthermore, we recognize that smoke's internal and external dispersion can pose significant threats to human life and impair evacuation processes. Therefore, we have developed cutting-edge source models that accurately simulate the smoke composition and flow rate resulting from fuel-rich or oxygen-rich combustion of complex hydrocarbon fuels.

Our team of experts utilizes state-of-the-art computational fluid dynamics (CFD) simulations to predict the dispersion of smoke both internally and externally. This includes accurate modelling of volumetric smoke source terms, toxic gas concentrations, and the effects of atmospheric conditions on smoke dispersion.

We go beyond conventional CFD simulations by considering the combinative nature of hazards due to toxicants and irritants within the smoke, such as carbon monoxide, carbon dioxide, oxygen depletion, and hydrogen cyanide. We can immediately indicate whether escape or muster is possible and safe by calculating an overall time-to-incapacitation or time-to-death due to these effects.

Our smoke modelling capability also includes estimating smoke visibility within an internal structure, such as an accommodation block, during a galley fire. In addition, we provide a range of key outputs from our smoke dispersion analysis, including smoke concentration isosurfaces indicating the dispersion of combustion products, concentration contours for various toxic gases, and time-to-incapacitation and time-to-death contours due to smoke inhalation.

We are committed to providing the most advanced and accurate smoke modelling services to ensure the safety of your personnel and assets. Contact us today to learn more about our smoke modelling capabilities and how we can assist you in preparing for accidental fire events.
