This study aims to identify the key design factors of a large-scale calorimeter and evaluate accuracy simulation results using Fire Dynamics Simulator (FDS) program. The specifications domestic were analyzed determine modeling input conditions for simulation. temperature, mass flow rate, oxygen concentration reduction inside duct compared with experimental heptane pool fires diameters 1.1 m, 1....

Fire whirl is a rotating fire with either a fixed or revolving flame centre-core caused by unbalanced entrainment. In general, the flame height of a fire whirl is significantly larger than that of a free standing fire. It is suggested by several studies that fire whirl is a disastrous scenario especially in urban or bush fires since it can greatly promote the fire spread and escalate the thread...

The occurrence of a fire, no matter how small, often exposes objects to significant levels of contamination from the products of combustion. The production and dispersal of these contaminants has been an issue of relevance in the field of fire science for many years, though little work has been done to examine the contamination levels accumulated within an enclosure some time after an incident....

Due to steadily increasing problem sizes and accuracy requirements as well as storage restrictions on single-processor systems, the efficient numerical simulation of realistic fire scenarios can only be obtained on modern high-performance computers based on multi-processor architectures. The transition to those systems requires the elaborate parallelization of the underlying numerical concepts ...

Smoke extraction systems, either static with natural ventilation, or dynamic mechanical ventilation are required to keep smoke layer at high levels in many tall atria. It is observed that a design fire heat release rate (HRR) commonly used for designing vents, but low HRR system. This will not produce sustainable environment. There no internationally agreed on guides determine the different sys...

Background In most wildland–urban interface (WUI) fires, damage to buildings results from poor surrounding vegetation management. No simulation had been conducted yet on historical WUI fires with Computational Fluid Dynamics modelling. Aims It was interesting check the feasibility of this modelling in simulating past fire cases for different scenarios management and propagation. Methods We stud...

The present paper studies the fire-induced pressure evolution in an air-tight compartment. Two cases with different sizes (i.e., 0.3 m × and 0.5 m) of square methanol pool fire are considered. Repeated tests were performed for each case, leading to a total four experiments. leakage compartment is measured under conditions order obtain relationship between increase. inside reaches peak values 13...

Air conditioning systems have become essential equipment in many buildings. However, fire safety design and management buildings rarely consider whether to turn the system off or keep it on a fire. This study ignites stack of wood room center corner explore influence air inlet actions fan coil unit (FCU) with door opened closed. Simulation results using Fire Dynamics Simulator (FDS) demonstrate...
