Numerical Simulation Of Indoor Fire

In a variety of fire, indoor fire has the biggest and most direct harm to people. Building all types of people engaged in production and life of the main premises, property is also extremely concentrated areas, because the construction of indoor fire damage caused very serious and direct impact on human life and safety. How to advance the difficult problem to fire science and validity of indoor fire protection is a science researcher. It is the most needed solution to research the process and aracteristic of fire and to use it during design by starting from fundamental study.On the basis of earlier research achievement, this paper advances the dynamic simulation of fire source. After analyzing the manner of different fire source it choose the model of fire spread on horizontal. In numerical simulation of the fire, the field simulation, regional simulation have their own advantages and shortcomings, therefore, this article will simulate the two together, play to their respective strengths, overcome their shortcomings. In this paper, the indoor fire process of use fire of software (FLUENT, CFAST), a typical architecture and interior structure fire load as an example, the use of field simulation software FLUENT the construction of the switch to single-room door, whether objects and smoke control of gas The impact of flow and temperature. CFAST use of regional simulation software for a single-room objects and objects were burning ignited the simulation, a multi-room sprinkler system in case there's smoke and temperature simulation. To achieve the development of indoor fire the two-dimensional field simulation studies and regional simulation. Through the simulation results and building fire and smoke control flow of contrast, reflects the basic simulation confirmed the fire smoke flows.This article on indoor fire to simulate the process, It is valuable for analyzing the fatalness of compartment fire and evaluating the fire protection design.
