Experiments have been carried out in a constant volume chamber to investigate the effects of Chlorella oil addition on the laminar burning velocity and Markstein length of Chlorella oil/RP-3 kerosene blends at an initial pressure of 0.1 MPa and temperature of 450 K over a wide equivalence ratio range from 0.8 to 1.4. The result shows that at equivalence ratios of 0.9 and 1.1, with the increase of Chlorella oil addition, no cellular structure is observed in the flame propagation images. It means that the Chlorella oil addition has little effect on the flame stability under these experimental conditions; however, at an equivalence ratio of 1.3, with the increase of Chlorella oil addition from 0 to 0.5, the flame tends to be stable. It is found that the Markstein length of Chlorella oil/RP-3 blend decreases with the increase of the equivalence ratio. The blend with 0.5 Chlorella oil addition has a more rapid decrease in Markstein length compared with that of the RP-3 between the equivalence ratio from 1.1 to 1.3. The peak laminar burning velocity of Chlorella oil/RP-3 kerosene blend is obtained at the equivalence ratio of 1.1, and with the increase of Chlorella oil addition from 0 to 0.5, the laminar burning velocity increases about 20%.

小球藻油/ RP-3煤油共混物层流燃烧速度和马克斯坦长度的实验研究
在恒定容积的室内进行了实验，以研究在0.1 MPa的初始压力和450 K的温度下，小球藻油的添加对小球藻油/ RP-3煤油混合物的层流燃烧速度和马克斯坦长度的影响。当量比范围从0.8到1.4。结果表明，当当量比为0.9和1.1时，随着小球藻油添加量的增加，在火焰传播图像中未观察到细胞结构。这意味着在这些实验条件下，添加小球藻油对火焰稳定性几乎没有影响。但是，当量比为1.3时，随着小球藻油添加量从0增加到0.5，火焰趋于稳定。发现小球藻油/ RP-3混合物的Markstein长度随当量比的增加而减小。在当量比从1.1到1.3时，与RP-3相比，添加了0.5绿藻油的共混物的Markstein长度降低得更快。绿藻油/ RP-3煤油共混物的当量比为1.1时，层流燃烧峰值速度为0，随着绿藻油添加量从0增加到0.5，层流燃烧速度增加了约20％。
