The prediction and verification of CO production rate based on extended mixture-fraction method

摘要

The paper uses both single-step and two-step reaction models to predict the yield of CO in a standard room with the half size of ISO9705 under different ventilation situations, and verify the validity of calculation results with the comparison against experimental data. The results show that the two-step combustion model can predict the yield of CO more precisely as long as under a proper grid and boundary setup. In practical researches of human evacuation and toxic gases, the method of FDS5 simulation can be used to predict gas yields which can do practical instructions.
