Abstract

Micro-combustors are frequently exposed to sudden changes in operating conditions, leading to flame breakage and fuel leakage, which is not conducive to clean combustion and sustainable development. In this paper, the changes in flame behavior in micro-planar combustors is numerically simulated under sudden changes in velocity, equivalent ratio, inlet temperature and compound conditions. According to the findings, the sudden increase in velocity (8–12 m/s) results in 3.1 mm flame backward and 3.91 % combustion efficiency decrease, while sudden decrease (12-6 m/s) forces the flame position to move forward 6.8 mm and increases combustion efficiency by 5.99 %. Besides, the sudden change of the equivalent ratio has the most significant impact on combustion efficiency, with a maximum difference of 16.63 %. The sudden increase in temperature has a positive effect on combustion efficiency and flame position, which is the result of inlet preheating, and the opposite effect is negative. Finally, under compound conditions, it is found that the sudden changes in fuel equivalent ratio and inlet velocity are the primary factors influencing changes in combustion efficiency. This study elaborated the combustion characteristic changes under single and compound conditions, which has important reference values for combustion under different operating conditions.
