Combustion and emissions of RP-3 jet fuel and diesel fuel in a single-cylinder diesel engine

Frontiers in Energy 2023, Volume 17, Issue 5, Pages 664-677 doi: 10.1007/s11708-021-0787-3

Abstract: The combustion characteristics and emission behaviors of RP-3 jet fuel were studied and compared to commercialcrank angle (CA) after top dead center (ATDC)) were adjusted to evaluate the engine performances of RPIn comparison to diesel fuel, RP-3 jet fuel shows a retarded heat release and lagged combustion phaseAs a result, RP-3 jet fuel features a longer ignition delay (ID) time, a shorter combustion durationCompared with diesel fuel, the nitrogen oxides (NO_x) emissions of RP-3 jet fuel are

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: The spray auto-ignition characteristics of RP-3 jet fuel and its three surrogates, the 70% mol -decaneas the two surrogates were designed to capture the H/C ratio (Surrogate 1) and DCN (Surrogate 2) of RPSurrogate 3 could emulate more physiochemical properties of RP-3 jet fuel, including molecular weightExperimental 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.

Optimal dome design considering member-related design constraints

Tugrul TALASLIOGLU

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 5, Pages 1150-1170 doi: 10.1007/s11709-019-0543-5

Abstract: This study proposes to optimize the design of geometrically nonlinear dome structures. A new Multi-objective Optimization Algorithm named Pareto Archived Genetic Algorithm (PAGA), which has an ability of integrating the nonlinear structural analysis with the provisions of American Petroleum Institute specification is employed to optimize the design of ellipse and sphere-shaped dome configurations. Thus, it is possible to investigate how the qualities of optimal designations vary considering the shape, size, and topology-related design variables. Furthermore, the computing efficiency of PAGA is evaluated considering six multi-objective optimization algorithms and eight quality measuring indicators. It is shown that PAGA has a capability of both exploring an increased number of pareto solutions and predicting a pareto front with a higher convergence degree. Moreover, the inclusion of shape-related design variables leads to a decrease in both the weights of dome structures and their load-carrying capacities. However, the designer easily determines the most requested optimal design through the archiving feature of PAGA. Thus, it is also demonstrated that the proposed optimal design procedure increases the correctness degree in the evaluation of optimal dome designs through the tradeoff analysis. Consequently, PAGA is recommended as an optimization tool for the design optimization of geometrically nonlinear dome structures.
