On the Origin of Oscillatory Instabilities in Diffusion Flames
확산화염의 진동불안성의 기원에 대해서
Abstract
Fast-time instability is investigated for diffusion flames with Lewis numbers greater than unity by employing the numerical technique called the Evans function method. Since the time and length scales are those of the inner reactive-diffusive layer, the problem is equivalent to the instability problem for the
