Activation Energy Asymptotics Revisited (I) - Quasisteady Extinction Conidtion of Diffusion Flames
활성화에너지점근법의 재고찰(I) - 확산화염의 준정상소화조건
Abstract
Activation energy asymptotics (AEA) for Linan#s diffusion-flame regime is revisited in this paper. The main purpose of the paper is to carefully re-examine each AEA analysis step in order to clarify the some concepts that are often misunderstood among the ordinary practitioners of the AEA. Particular attention is focused on the different AEA regimes arising from the double limit of large Zel#dovich and Damkohler numbers. In addition, the expansion procedures are shown in detail and the method that the turning point condition, commonly known as the Linan#s extinction condition, is found is explained.
