Spatial modeling analysis device and method of combustible materials

Abstract

The invention discloses a spatial modeling analysis device and method of combustible materials. The device comprises a storage module (3), a decomposition module (2), a modeling module (4), a space division module (5), a statistics module (7) and a display module (8), wherein the storage module (3) prestores the weight and the combustion characteristic parameters of all combustible materials in a space used for containing the combustible materials; the decomposition module (2) divides the space into a plurality of subspaces; the modeling module (4) carries out three-dimensional modeling on each subspace; the space division module (5) further divides each subspace subjected to the three-dimensional modeling into a plurality of space units; the statistics module (7) calculates the heat and the toxic smoke amount, which are released in each second, of the combustible materials and the sustained combustion time of the combustible materials in each space unit and whole space; and the display module (8) displays the sustained combustion time, the released heat, the toxic smoke amount and the temperature of the combustible materials. The heat and the toxic smoke amount, which are released when the combustible materials are burnt, a change situation of surrounding space temperature along with time and a fire propagation situation can be scientifically and precisely predicted.

Description

technical field [0001] The invention relates to the technical field of fire early warning, in particular to a space modeling analysis device for combustibles. Background technique [0002] The main hazards of fire come from heat and smoke, and the greatest hazard is caused by heat. [0003] Predicting fire development by numerical simulation is an effective way to study fire. Due to the arbitrariness of its parameter setting and the reproducibility of the prediction results, many achievements have been made in the numerical prediction of fire development by using this method. The prerequisite for the application of numerical simulation methods is to establish a correct and credible fire mathematical model. Fire models are divided into field model, zone model, network model and expert model. In the fire analysis model, it is necessary to model the combustible (or ignition source), usually as a particle in space, and use uniform combustion characteristic parameters. [0004...
