An experimental study of combustion in a cylindrical meso-scale combustor with a strong cwirling of pre-mixed propane-air mixture was made. We measured the basic parameters of the flame at the chamber exit: temperature profile along the cylindrical tube chamber, the gas composition of the reaction products of combustion, the emission spectrum of the flame at the base of the camera. The ultimate goal of the studies is to find stable combustion regimes in small-sized combustion chambers.
