Effect of Cooling Air on Swirl Combustor

Journal of Mechanical Engineering, 1970
This paper presents the numerical study of the turbulent swirling flow in a combustor and the effect of cooling air, which has practical applications in industrial furnaces and jet engines. Cooling air is used to protect the combustor wall from burnout, while allowing the combustion to occur at higher temperature.
