Simulation analysis on mathematical model in conflagration of interior area

A mathematical region model of indoor fire is established. Hypotheses are made on the distribution of gas consistency is even, the layers of cold air and hot air are discontinuous, and the indoor pressure and the pressure of outdoor are not different, etc. The theoretical analysis of the simulation model is according to the classical Theories of Conservation of mass and Persistence of energy that are used to derive the formulae for the computer programming, and also as the theoretical bases for the analysis. Using the thought of object compiling and with VB as an instrument to carry on the development of program that gives out the thought to compile program and the calculation flow chart of correlation. The correctness for this program of simulation model is proved by the experimental date that was carried out by a Fire Fighting Research Institute.
