Theoretical Study of Triple-Flame Temperature Distribution in Heat-Recirculated Microcombustor

Abstract

This paper presents a two-dimensional analytical method for investigating the triple-flame temperature profile in a microcombustor. For this purpose, the microcombustor chamber is divided into a preheat and a reaction zone and the role of heat recirculation from the flame zone into the preheat zone is taken into account in this research. It is indicated that the maximum temperature is strongly dependent on this phenomenon. This analysis is done by applying the energy conversion equation in each zone and then solving these equations along with required boundary and matching conditions by the use of partial differential equation method. The outcome of this research leads to the temperature profile in preheat and flame zone, and also the effects of combustor characteristics on the temperature distribution.
