摘要

在初始压力0.1 MPa、初始温度450 K和当量比范围0.8~1.2工况下

进行小球藻油及其与RP-3航空煤油混合燃料的层流燃烧特性研究。研究结果表明:随着当量比增加

小球藻油着火滞燃期缩短

拉伸火焰传播速度增加。与RP-3航空煤油相比

小球藻油无拉伸火焰传播速度峰值更偏向于浓混合气区域

且对当量比较为敏感

随着当量比增加

其无拉伸火焰传播速度变化显著。随着小球藻油含量增加

混合燃料无拉伸火焰传播速度峰值右移

50%小球藻油/50%RP-3航空煤油混合燃料无拉伸火焰传播速度峰值出现在当量比Φ=1.4附近。研究发现

与小球藻油和RP-3航空煤油单组分燃料相比

50%小球藻油/50%RP-3航空煤油混合燃料马克斯坦长度值变大

混合燃料具有较好的燃烧稳定性。

Abstract

The laminar combustion characteristics of chlorella oil and its blends with RP-3 kerosene were examined at initial pressure of 0.1 MPa

initial temperature of 450 K and equivalence range of 0.8-1.2 conditions. The results showed that with the increase of equivalence ratio

the ignition delay period of chlorella oil decreased and the stretched flame speed increased. Compared with RP-3 kerosene

the peak value of unstretched flame speed of chlorella oil was more shifted to the region of rich mixture

and the unstretched flame speed of chlorella oil was more sensitive to equivalence ratio. It was observed that with the increase of equivalence ratio

the unstretched flame speed of chlorella oil varied significantly. With the increase of chlorella oil addition

the peak value of unstretched flame speed shifted to right

the peak unstretched flame speed of the mixed fuel with 50% chlorella oil and 50% RP-3 appeared near the equivalence ratio of 1.4. It was found that compared with chorella oil and RP-3 single fuel

the Marksein length of the mixed fuel was more larger

indicating the combustion of the mixture with chlorella oil and RP-3 is more stable.
