Methanol 연료 액적의 연소 특성에 관한 연구 = Contributed Study on the Combustion Characteristics of Methanol Fuel Droplet

다국어 초록 (Multilingual Abstract)

The main purpose of this study is to provide basic information of droplet burning, extinction process and flame behavior of methanol fuel and improve the ability of theoretical prediction of these phenomena. For the improved understanding of these phenomena, this paper presents the experimental results on the methanol droplet combustion conducted under various initial droplet diameters (d0), ambient pressure (Pamb), and oxygen concentration (O2) conditions. To achieve this, the experimental study was conducted in terms of burning rate (K) with normalized droplet diameter (d/d0), flame diameter (df) and flame standoff ratio (FSR) under the assumptions that the droplet combustion can be described by both the quasi-steady behavior for the region between the droplet surface and the flame interface and the transient behavior for the region between the flame interface and ambient surrounding.
