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.
