An experimental study on spray auto-ignition of RP-3 jet fuel and its surrogates

Yaozong DUAN, Wang LIU, Zhen HUANG, Dong HAN

Frontiers in Energy 2021, Volume 15, Issue 2,   Pages 396-404 doi: 10.1007/s11708-020-0715-y

Abstract: In the latter case, fuel spray auto-ignition behavior is an important index for engine operation reliabilityThe spray auto-ignition characteristics of RP-3 jet fuel and its three surrogates, the 70% mol -decaneExperimental results indicate that Surrogate 1 overestimates the auto-ignition propensity of RP-3 jetfuel, whereas Surrogates 2 and 3 show quite similar auto-ignition propensity with RP-3 jet fuel.Therefore, to capture the spray auto-ignition behaviors, DCN is the most important parameter to match

Rules Auto-conditioning Fuzzy Controller

Cheng Jin,Zhang Chenghui,Xia Dongwei

Strategic Study of CAE 2003, Volume 5, Issue 9,   Pages 78-81

Abstract:

According to the fuzzy theory and practical experience, the authors propose a rules autoconditioning fuzzy controller, whose dynamic performance and stability are all prior to the conventional PID controller and the basic fuzzy controller. It is also shown that the controller has good disturbance rejection properties and insensitivity to plant parameter variations. Both simulation and engineering prove that it is feasible actually and convenient to put into practical control project.
