Abstract
ABSTRACT Present work deals three families of SiO 2 gelling agents which have been used to produce gel fuel based on Kerosene. Jet A-1 is chosen as fuel where power-law rh eological model is used to confirm whether or not the gelification is achieved depending on the %wt of gellant. It was confirmed that the produced jelly-like substance have shear-thinning effect, and t hat its apparent viscosity increases as SiO 2 concentration increases. Compared to other gellants, gel with AerosilⓇ R972 fits most to the power-law model, while gels with Silica 230 and Silica 530 deviate from the power-law model. The rheological characteristics behaved differently depending on th e mixing method(vortex mixing and manual mixing) when gellant concentration is increased.초 록 본 연구에서는 SiO 2 계열 젤화제로 알려진 AerosilⓇ R972, Silica 230, Silica 530을 사용하여 케로신 기반 젤 연료를 제작하였다. 케로신 계열 연료로는 Jet A-1을 사용하였으며 젤화(gelification) 여부를 확인하기 위한 전단박화(shear thinning) 현상은 멱법칙(power-law) 모델을 이용하여 검증하였고 제작된 모든 젤 연료는 전단박화 효과와 함께 SiO
