Effect of Equivalence Ratio on Propagation Process of Combustible Gas in Venting Tube

Abstract:

To explore the effect of equivalence ratio on the propagation process of combustible gas in the venting tube, in the present study, the κ-ε turbulent model and the combustion models were implemented base on unaltered venting conditions and different equivalence ratio of methane-air. In particular, the numerical simulation results illustrate both speed and pressure were at maximum when equivalence ratio was 1.0. However, methane-air didn't reach the most sufficient combustion when equivalence ratio was 1.0. It was possible that the pressure release caught the equivalence ratio change and failed to generate detonation.
