Abstract
Based on the qualitative consideration that the flow continuance in the combustor may play an important role not only in combustion enhancement but also in heat transfer enhancement, main attention will be paid on it in the cooling period after the pressure in the combustion chamber attains its maximum. Three types of constant volume combustors are used; a cylindrical combustor with a hemi-sphere-shaped divided chamber, a cylindrical combustor with a pan-cake-shaped divided chamber, and a fan-stirred combustor. A simple cylindrical-shaped combustor is also used for obtaining standard combustion characteristics. Enhancement behaviors of combustion and heat transfer are examined by analyzing the pressure histories after the spark ignition. Flow visualization is also made of the flow pattern in the fan-stirred combustor. It is found that the fan-stirred combustor can realize and maintain a complex flow pattern in the cooling period, and that it combines strong heat transfer enhancement effects with moderate combustion enhancement effects.
