原木楞堆燃烧实验与数值模拟研究

Research on combustion experiment and numerical simulation of log pile

通过大空间燃烧实验,研究楞堆燃烧过程中温度场的变化情况,采用FDS软件模拟楞堆燃烧温度场。实验结果与模拟结果的对比分析表明,FDS可以大致模拟原木楞堆燃烧过程中温度场变化规律,模拟曲线比实测温度变化平稳,并分析实验结果和模拟结果存在差异的原因。

By a full scale combustion experiment with log pile, we studied the characteristics of temperature field changes, and the simulation method of FDS software was used. By contrasrive analysis, it was showed that the log pile temperature field in the combustion process could be simulated by FDS software. Simulation curve changed more smoothly than the measured temperature. The reasons of differences between experiment resuits and simulation results were analyzed.
