摘要：
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. © 2019, Editorial Department of Journal of Aerospace Power.
