• Continued from the 1 st Report, in which the combustion gas flow through a single chamber was analyzed, this paper presents the theory of gas flow through a typical annular combustion chamber of a gas turbine or a jet engine by using the thermo-aerodynamical analysis. By one numerical calculation, it was quantitatively shown that : (1) the cooling air which flows the outer space of annular combustion chamber enters naturally into the inner space through the mixing holes by the pressure difference between outside and inside and (2) it prevents the increase of temperature of combustion gas and it promotes the increase of gas velocity, while it causes a large pressure drop by mixing in addition to that by friction and expansion.
