Abstract
Premixed methane-air combustion affected by forced vortex is numerically simulated in a cylinder tube. The effects of inlet velocity and angular velocity of premixed gas on stability of flame in different equivalence ratios are analyzed. The results show that when the position of flame front is fixed, inlet velocity and angular velocity are dependent linearly with few differences among all linear coefficients. The radius of flame and thermal efficiency both decrease when swirling becomes more intensive, but the thermal efficiency can be enhanced by changing the distribution of inlet velocity. The combustion features are completely informed and analyzed in the results in this paper, the results offer a theoretical prediction of the practical stable burner.
