剪切对凝胶汽油表观粘度影响的实验研究
Experimental study on the influence of shear on apparent viscosity of gelled gasoline
摘要
Abstract
The silica⁃based gelled gasoline,QNJ⁃1 and QNJ⁃2 were respectively prepared by means of ultrasonic vibration and mechanical stirring.The apparent viscosity of the gelled gasoline was researched experimentally by rotational rheometer with cone⁃and⁃plate configuration.The effect of gel content,shear rate and pro⁃shear on apparent viscosity of the gelled gasoline was analyzed in this paper. The results indicate that apparent viscosity increases with the increment of the gelling content. The phenomenon is ob⁃served obviously at low shear rate;the apparent viscosity when gelling content maintains decreases with shear rate increasing.The ap⁃parent viscosity of the gelled gasoline would be reduced by pro⁃shear significantly.The research results are of important significance for further investigation of effect of the gelled gasoline viscosity on the atomization mechanism.关键词
