Fire simulation and smoke spread analysis of subway stations at different fire locations

نویسندگان

چکیده

In order to explore the law of smoke spread in fire environment an island-style subway station, this article takes as research object. Based on dynamics, pyrosim is used establish a model observe concentration and temperature changes under different locations. The study found that when source at end platform layer, flue gas farthest evacuation channel safety exit reaches 80% 85s 130s, respectively, nearest are 32° 28° respectively. When middle 70s 105s exceeds 40°.

A Network Fire Model for the Simulation of Fire Growth and Smoke Spread in Multiple Compartments with Complex Ventilation

There is a need for fire modeling tools capable of rapid simulation of fire growth and smoke spread in multiple compartments with complex ventilation. Currently available tools are not capable of simulation of complex ventilation arrangements in a timely manner. To address this problem, a new fire model called Fire and Smoke SIMulator (FSSIM) has been developed. FSSIM is a network model whose c...

WRF-Fire Simulation of Lateral Fire Spread in the Bendora Fire on 18 January 2003

On the afternoon of 18 January 2003, a number of separate fires located to the west of Canberra, Australia, began major runs under extreme fire weather conditions, and impacted upon the city. These events were well documented by a range of instruments, including a multispectral line-scanning instrument attached to an aircraft. Analysis of the data collected revealed that a number of the fires h...

Smoke Simulation for Fire Engineering using CUDA

Computational solutions to the Navier-Stokes equations for fluid dynamics has become an increasingly useful tool for engineering purposes. However, solving fluid dynamics accurately requires a considerable amount of time and computer resources. In this thesis we investigate the possibilities of interactive smoke simulation for engineering purposes, using the recently released programming model ...

Coverage Analysis of Fire Stations Located in Puebla City and Determination of New Possible Required Locations

The growing population in Puebla City these last couple of years entailed the expansion of its original urban area. The most recent settlements have established on areas that are highly exposed to natural disasters, thus, requiring the proper emergency service coverage provided by Fire Stations. To assure this kind of service coverage, the current fire stations in Puebla City were evaluated thr...

A convection model for fire spread simulation

We present a convection model which can be coupled with fire propagation models in order to take into account the wind and the slope which are two of the most relevant factors affecting surface fire spread. An asymptotic analysis gives a three dimensional convective model governed by a two–dimensional equation.
