摘要
针对新型灭火训练装置准确表现室外无风条件下运用开花水枪灭油池火过程的火焰变化规律问题,根据油火燃烧特性,基于系统动力学模型,给出了灭火过程的指数型火焰变化趋势解析形式。结合实际灭火训练数据和FDS仿真结果对灭火过程的系统动力学模型进行修正,以Netlogo系统动力学仿真模型框架为基础,构建灭火过程火焰控制的数值仿真实验平台,确定了控制火焰变化的具体参数以及参数的取值范围和物理意义,运用仿真平台模拟了人员灭火典型动作状态下的火焰变化控制过程,给出了火焰变化规律控制参数表,为新型消防训练装置控制灭火过程提供途径。
To the question of the new firefighting training device simulating the process of destroying oil pool fire under the windless and outdoor condition with flowering nozzle, according to the oil fire burning characteristics, and based on a system dy- namics model, an exponential type flame extinguishing process trends in analytical form was supplied. The system dynamics model was revised by actual firefighting training data and FDS simulation results. Based on the Netlogo system dynamics sim- ulation model framework, a numerical simulation platform was built for the extinguishing processes. Flame control parameters and the specific parameters change range were determined as well as the parameters＇ physical significance. Using the simula- tion platform simulating the flame change control process for the staff typical extinguishing action status, the flame changes of control parameter table was given, and provides a wayto control extinguishing process for the new firefighting training device.
