The importance of graph search algorithm choice to the directed relation graph with error propagation (DRGEP) method is studied by comparing basic and modified depth-first search, basic and R-value-based breadth-first search (RBFS), and Dijkstra’s algorithm. By using each algorithm with DRGEP to produce skeletal mechanisms from a detailed mechanism for nheptane with randomly-shuffled species or...

Detailed kinetics mechanisms for plasma-assisted combustion contain numerous species and reactions that model the interplay between non-equilibrium plasma processes hydrocarbon oxidation. While physically accurate comprehensive, such detailed are impractical simulations of unsteady multi-dimensional discharges their effect on reactive mixtures in practical devices. In this work, we develop appl...

The work was supported by OTKA fund T68256. Abstract—A new species reduction method called the Simulation Error Minimization Connectivity Method (SEMCM) was developed. According to the SEM-CM algorithm, a mechanism building procedure is started from the important species. Strongly connected sets of species, identified on the basis of the normalized Jacobian, are added and several consistent mec...

• A 5-component reduced mechanism for diesel-biodiesel-gasoline blends is proposed. Multiple DRG, DRGEP and FSSA methods are applied on the detailed mechanisms. Cross-reactions Arrhenius parameters optimisation techniques analysed. Reduced multicomponent mechanisms validated against literature data. Multicomponent accurately replicates ignition-related characteristics. In this study, a compact ...

For several years now plasma assisted combustion has been the subject of intense research due to stabilization effects a can have on flames. Particularly, experiments shown promising impact Nanosecond Repetitively Pulsed discharges while not exceeding an energy consumption few percent flame power. In this work, incremental methodology with step-by-step approach used build single mechanism upon ...
