Abstract:

Experimental trajectories of the flame in homogeneous and non-homogeneous mixtures were compared with analytically obtained ones. The study led to the following conclusions 1 The optimum location of the point of ignition is at the periphery of the combustion chamber for both, homogeneous and nonhomogeneous, gas mixtures because this flame origin produces the strongest vortex. 2 Combustion of a nonhomogeneous gas mixture provides greater time rates of energy emission than that of a homogeneous mixture, however, produces a stronger swirl than that of a nonhomogeneous mixture when both are overrich. 3 At the beginning of the combustion the experimentally observed trajectories of the flame coincide with the theoretically determined trajectories, but in the later portion of the combustion they do not because the drag on the in flamed portion of the mixture exceeds that predicted by theory.
