The intermediate products C13—C18 of algae-based aviation kerosene were blended with aviation kerosene at a ratio of 10%

and the spray atomization performance of blended fuel oil was compared. In this experiment

as the carbon number of blended linear paraffins grew

the effect of atomization on fuel spray gradually increased. Among them

the linear alkanes C18 was blended at a ratio of 10%: the maximum reduction of the atomizing cone angle was 5.07%; the average droplet speed was changed by a maximum of 17.6%; Sauters average diameter was changed by a maximum of 15%; Ohnesorge number and Weber number significant changed with increasing injection pressure

affecting the secondary breakage of droplets. In general

the addition of long linear alkanes will have a certain influence on the atomization performance of aviation kerosene.
