Abstract
In this paper, we investigate numerically the influence of heat loss and Damköhler number, which is inversely proportional to the square of strain rate, on the edges of premixed flames in a two dimensional counterflow for Lewis numbers greater than unity. The propagation speed of flame edges is plotted against Damköhler numbers for different values of the heat loss parameter showing a multiple flame edge solutions in the form of S shaped curves.
