IDEALIZED 2-DIMENSIONAL FLAMES IN PREMIXED SYSTEMS

Idealized, two dimensional combustion is considered in terms of irrota tional, premixed gases upstream of a discontinuous flame which propaga tes with a constant specified velocity and results in a specified decr ease in density. The flame is anchored by a small flame-holder which i s located on the lower wall and which plays an essential role in deter mining the flow. With heat release the Bow downstream of the flame is rotational and involves a stagnation region adjacent to the upper wall . Numerical solutions are obtained for a range of propagation speeds d own to roughly 0.70 of the velocity of the approaching stream and for several density jumps including the zero heat release case. In this la tter case the assumed influence of the flame holder results in flow no nuniformity.
