摘要

Abstract

Crimped ribbon flame arresters are important safety devices in the chemical industry

especially for the dangerous situations. Although proper design of arresters by the numerical simulation method is promising

its reliability and accuracy are dependent upon the mathematical model. In this work

an integrated mathematical model for the microchannel in the crimped ribbon flame arresters was set up; the fluid flow behavior and the sensitivities of four chemical kinetics mechanisms of propane-air on the accuracy were analysed. It is shown that turbulence is predominant in the microchannel of the crimped ribbon flame arresters under the deflagration and detonation conditions

and a new quenching criterion for the numerical simulation is proposed. The kinetics mechanism of Mansouri et al. among the four ones is the most accurate due to the best agreement of the predicted outlet temperature at the experimental flameproof velocity with the autoignition temperature of propane-air. The species mass fraction profiles and the temperature distribution

which are too difficult to measure due to the tiny dimension of the microchannel in experiments

are captured. The fundamental insights into chemical reactions and heat loss are well portrayed. It can be concluded that the integrated mathematical model established in this work can be used as a reliable tool for modeling

selecting and designing such type of crimped ribbon flame arresters with the propane-air medium in the future.
