Abstract

The dimensionless extinction constants of particulate matter for F-76 diesel and JP-8 aviation fuels were measured at both 633 nm and 853 nm in the transmission cell where the simultaneous gravimetric measurement of PM concentration is compared to the light extinction measurement. For the F-76 diesel PM, the average value of the dimensionless extinction constants at 633 nm was 8.8 whereas that of the dimensionless extinction constants for JP-8 was 9.8 at the same wavelength. As the wavelength is increased to 853 nm, the average value for the F-76 diesel was reduced to 8.2 whereas that for JP-8 was decreased to 8.9.

F-76 선박용 디젤유와 JP-8 항공유의 연소과정에서 발생되는 입자상물질(PM)의 무차원 광소멸계수를 Transmission Cell를 이용하여 측정하였다. 무차원 광소멸계수의 측정방식은 각각 광원의 파장길이가 633 nm와 853 nm인 대역에서 중력식 필터법에 의해 채집된 PM의 농도와 광학적 방법에 의해 측정된 PM의 농도를 비교하는 방법을 통해 이루어졌다. 광원의 파장길이, 633 nm 대역에서 측정된 무차원 광소멸계수는 F-76의 연료에서 발생된 PM의 경우 8.8인 반면 JP-8 연로부터 생성된 PM의 경우 9.8이였다. 한편 광원 파장길이가 853 nm로 증가함에 따라 두 연료 모두에서 발생된 PM의 무차원 광소멸계수는 각각 8.2 (F-76)와 8.8 (JP-8)로 감소하는 경향을 나타내었다.
