“…FDS data has been verified to be able to provide accurate fire dynamic results [19], and 3D rendering technology has also been verified to be very suitable for integration with FDS grid data [20]. Therefore the combination of FDS data and 3D rendering technology makes a perfect tool for simulating accurate and realistic smoke.…”

Abstract. Fire is one of the major disasters that often happen in the cities. It causes serious economic losses and casualties. Smoke is the main cause of death in fire and it is difficult to be simulated in the traditional way of fire drill. A multi-role collaborative fire drill simulation system was developed on the basis of virtual reality and server engine technology. The system consists of the client end and the server end. In the client end, the realization of the virtual fire scenes is based on the VIZARD software, which allows the trainees to experience a realistic and yet non-threatening fire scenes. The KBENGINE framework is used to enable multi-role synchronous login, the participants can collaborate in a virtual fire drill without time or space constraints. In order to carry out effective virtual training, Fire dynamics data and three-dimensional rendering technology has been especially designed to create a realistic and accurate smoke environment. The smoke risk evaluation model was introduced to assess the safety of different evacuation routes so that trainees could identify the safest route to escape. The test results show that the system has good performance and high accuracy, which helps trainees learn the knowledge of firefighting in the low-cost, high-security, high-fidelity and repeatable virtual environment, and accumulate the real-world firefighting combat experience.

The problem of emergency evacuation of public buildings intended to accommodate large numbers of people is critical. Modern technologies such as the use of numerical simulations, virtual and augmented reality, and Agent Based models represent an opportunity to study behaviors that are difficult to reproduce in real life (e.g. explosions and fires emergencies). This may allow to improve new and existing structures with respect to such risks and therefore to improve the resilience of modern communities. In this paper, the problem of emergency fire evacuation for an existing school in the hinterland of Milan is studied. A virtual reality-based system for the simulation of fire emergency response will be developed starting from the BIM model and then moving on to a platform that ensures the interaction between human and the virtual simulation environment. The spreading of the flames and smoke is based on fire numerical simulation using computation fluid dynamic (CDF) software. Such simulation method may reproduce realistic fire processes and illustrate smoke movement by describing the configuration of fuel, ventilation, and fire source. The verification of the infrastructure response and the subsequent modification for a better emergency response represent the expected results of the research.

Computational tools have been developed at the National Institute of Standards and Technology (NIST) for modeling fire spread and smoke transport. These tools have been adapted to address fire scenarios that occur in the wildland urban interface (WUI) over kilometer-scale distances. These models include the smoke plume transport model ALOFT (A Large Open Fire plume Trajectory model) and WFDS (Wildland-urban interface Fire Dynamics Simulator) for fire spread and smoke transport in the wildland-urban interface. The visualization tool is called Smokeview. In this paper, an overview of the physical basis of the fire spread and smoke transport models will be discussed briefly along with the visualization of characteristic results using Smokeview. A technique will be described for visualizing smoke realistically and indications will be given how Smokeview can be applied to other fire models.
