Initiation of Gaseous Premixed Flame

예혼합기체 연료의 화염생성에 관한 연구

The flame initiation of an infinite fuel system exposed to a planar ignition kernel has been investigated numerically. The aim has been to promote an understanding of the flame initiation by using the simplest mathematical formulation which retains the essential physical features. It has been found that there exists a minimum ignition energy below which a combustion wave cannot be initiated. For a fixed value of Lewis number, the same flame progation velocity has been obtained irregardless of the amount ignition energy supplied. Furthermore, for a fixed energy input there is a maximum Lewis number over which the flame cannot be initiated.

본 연구에서는 이러한 예혼합기체의 유한두게의 고온기체에 의한 점화현상을 일차원 평면적으로 다룸에 있어 점화를 일으키는 고온기체의 두께와 기체의 물리적 성질의 비를 나타내는 Lewis수의 영향을 알아 보고자 한다.
