Abstract:

The mathematic models were established to study the distribution of the flow field and movement rule of the smoke in a transport aircraft cabin with environment control system when fires broke out. Based on the interaction of forced convection and natural convection, this article simulated and analyzed the changes of temperature fields and concentration fields of combustion product in initial stages of fire under different boundary conditions. Regularities of the propagation of harmful gases are provided by analyzing the concentration distribution of carbon dioxide. According to this article research results, we can upgrade and optimize the corresponding measures to tackle a fire. Namely, when a fire break out, the staff should be far away from the fire source, stay away from the cabin wall and increase the ventilation rate in low temperature to expand the living environment in space and time.
