Abstract

The interaction of a stoichiometric, laminar premixed methane/air flame with a coolant jet is investigated using two-dimensional fully resolved simulations (FRSs). The flame is forced at the inlet with velocity modulation and the coolant is injected from a cooling hole located on the wall at the same temperature as the premixture. FRS cases featuring a combination of blowing ratios, forcing frequencies, position of the cooling hole and the coolant type (air and N2) are studied to understand the effects of these parameters on flame dynamics and CO emissions. The results show a negligible impact of the forcing frequency on the exhaust CO emissions. However, increasing the blowing ratio and the..
