Experimental study on laminar flame speeds and chemical kinetic model of 2,4,4-trimethyl-1-pentene

Construction of a Chemical Kinetic Model of Five-Component Gasoline Surrogates under Lean Conditions

“…Whether the constructed chemical kinetic model can be used for the numerical simulation of the combustion process depends on the model’s prediction of the fuel combustion characteristics. The proposed mechanism has verified the combustion characteristics of pure component fuels under lean conditions based on extensive experimental data [ 16 , 26 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ] ( Supplementary Materials Figures S1–S10 ). This study will verify the combustion characteristics of multi-component alternative fuels from three perspectives—ignition delay time, laminar combustion speed, and concentration distribution of important combustion substances.…”

“…The simplified mechanism proposed by Zheng et al [ 30 ] is selected as the DIB sub-mechanism. This machine has 50 species and 361 elementary reactions, and it has good predictive performance in terms of ignition and flame speed.…”

“…In this study, a chemical kinetic model of a five-component gasoline fuel substitution mixture containing n-heptane, isooctane, toluene, DIB, and CHX is constructed. The model mainly includes three parts: (a) the TRF sub-mechanism is derived from our previous study of the TRF mechanism [ 10 ], and the toluene part of the macromolecular reaction is modified according to the simplified mechanism of Liu et al [ 11 ]; (b) the DIB sub-mechanism is derived from the model constructed by Zheng et al [ 30 ]; and (c) the CHX sub-mechanism is simplified from the JetSurF2.0 mechanism [ 26 ]. At present, no simplified version of the CHX mechanism has been found in literature.…”

“…In this study, the cyclohexane was chosen as a representative of gasoline naphthenes due to the simple cyclic structure. The CHX mechanism [ 26 ] is simplified under a wide range of conditions, and added to the DIB mechanism proposed by Zheng [ 30 ] and the TRF mechanism developed by our research group [ 10 ]. A five-element simplified mechanism for gasoline suitable for lean combustion is obtained.…”

A comprehensive experimental and kinetic modeling study of di-isobutylene isomers: Part 1

“…Revitalized interest in DIB as a fuel supplement inspired several recent flame studies summarized in Table 1 . Zheng et al [13] measured burning velocities of DIB-1/air flames in a constant volume combustion bomb at initial mixture temperatures of 400 and 450 K, at 1 and 3 atm, comparing linear and non-linear stretch correction approaches. These measurements were compared to the predictions of the kinetic model developed by Andrae and Kovács [14] , and the mechanism developed by the authors [13] .…”
