Two-dimensional steady-state simulations to understand the flame stability of a cylindrical backward-facing three-stepped microcombustor with a recirculation cup are performed in the current study. This model is initially validated by using data from preliminary experiments and also ensured the grid independence. The aim of the present study is to understand the effect of heat recirculation on flame stabilization in a stepped combustor. Various heat recirculation cup lengths, ranging from 10 to 50 mm, are considered for the present computation. The results show that an increase in cup length significantly improves the flame stability through mixture preheating. This study indeed helps in developing an optimized combustor that can be used as a heating source for power applications.
