【Abstract】 Aimed at the bad stiffness in the twin channel burner, the cold conditions outlet flow field of twin channel combustor was measured and explored by using PIV technology. The flow behaviors were analyzed and compared with cuneiform body added on different position of the combustor outlet. The structural parameter was obtained that can enhance the outlet velocity of the two strands primary airs and the stiffness of combustor outlet efflux without reducing the size of the inverse flow region. The study can be used for reference when rebuilding combustor in practice.更多还原
