This study presents numerical simulation of turbulent spray combustion within the planar sector for a 1000-hp class turbo-shaft engine reverse flow combustor. Simulation domain with three swirler cups corresponds to a sector of a full annular combustor and the grid also includes the annulus flow. A coupled Euler-Lagrange method models the two-phase reacting flow wherein chemistry and turbulence interaction is accounted for by the Eddy Dissipation Concept Model. Random Walk model is used to model the interaction between continuous and disperse phases. Combustion is modeled with a single step global reaction and its rate is limited by the Eddy Dissipation Concept Model. Results indicate the presence of hot spots at the exit plane at locations just across the injectors. The simulation suggests that some dilution jets over penetrate the cross flow with trajectories close to the liner across. This indicates the necessity for a design iteration.
