The problem of a flame stabilized by a line source of fuel of strength 2πκ is solved numerically for values of the Lewis number L < 1. In this parameter regime analytical studies as well as previous numerical studies have found stationary solutions corresponding to both axisymmetric and cellular flames. For sufficiently small values of L, we have computed time periodic pulsating cellular solutions in the form of travelling waves.
