Parametric Study of Effect of Geometric Configurations of Microjets in an Axisymmetric Dump Combustor Flow

Present day engineering and environment challenges demand the design of combustion systems to be lean and clean. Various flow control strategies have been studied to make them more efficient. In this study, microjets are used as a flow control measure and a parametric study of the geometric configurations is performed. Increasing the number of microjets decreases the outlet temperature, but increases the temperature near the inlet. Compared with no microjets configuration, outlet temperatures are higher with microjets. Species concentration at the outlet is also affected by the number of microjets. Least amount of unburnt fuel at the outlet was for the configuration with the highest number of microjets.
