    Investigation of thermal performance in dual‐fuel units by Xiaochun Xue, Yonggang Yu

    Published 2022-12-01
    “…The process was modeled using the Navier–Stokes equations with chemical kinetics and interior ballistic equations. The results show that the muzzle phenomena with large temperature gradients and different wave structures appear after the supersonic vehicle enters into the free‐flight stage. …”

    The GARD Prebiotic Reproduction Model Described in Order and Complexity by Christian Mayer, Doron Lancet, Omer Markovitch

    Published 2024-02-01
    “…Early steps in the origin of life were necessarily connected to the unlikely formation of self-reproducing structures from chaotic chemistry. Simulations of chemical kinetics based on the graded autocatalysis replication domain (GARD) model demonstrate the ability of a micellar system to become self-reproducing units away from equilibrium. …”

    Protobiotic Systems Chemistry Analyzed by Molecular Dynamics by Amit Kahana, Doron Lancet

    Published 2019-05-01
    “…One such model is the graded autocatalysis replication domain (GARD) formalism embodied in a lipid world scenario, which offers rigorous computer simulation based on defined chemical kinetics equations. GARD suggests that the first pre-RNA life-like entities could have been homeostatically-growing assemblies of amphiphiles, undergoing compositional replication and mutations, as well as rudimentary selection and evolution. …”

    Automated chemical resonance generation and structure filtration for kinetic modeling by Grinberg Dana, Alon, Liu, Mengjie, Green, William H.

    Published 2022
    “…Determining the representative reactive structures of chemical species is crucial for identification of reactive sites and consequently applying the correct reaction templates to generate the set of important reactions during automated chemical kinetic model generation. We describe a fundamental set of resonance pathway types, accounting for simple resonating structures, as well as global approaches for polycyclic aromatic species. …”

    Self-assembly in mechanical systems by Kwiecinski, J

    Published 2018
    “…We initially study the self-assembly of a filament, taken as a proxy for the cross-section of a biomembrane, which is primarily driven by the chemical kinetics of attaching proteins and find that, under certain mechanical stiffness regimes of the attaching proteins, pattern formation occurs. …”

    Development of an Extractive Reactor Block in the Aspen Plus Simulator by Ngu Ming, Tiong

    Published 2012
    “…The introduction of an in situ separation function within the reaction zone leads to complex interactions between liquid-liquid equilibrium, liquid-liquid mass transfer, intra-catalyst diffusion (for homogeneously catalysed processes) and chemical kinetics. The advantages of such alternatives is the use of simultaneous extraction and reaction to improve the yields and/or selectivity to the products, and also that they require smaller recycle flows. …”

    Periodic Variations of an Autowave Structure in Two-dimensional System of Parabolic Equations by Alina A. Melnikova, Natalia N. Deryugina

    Published 2018-02-01
    “…The scope of the system includes the description of autowave solutions in the field of ecology, biophysics, combustion physics and chemical kinetics. The approximate solution allows us to choose the model parameters so that the result corresponds to the processes observed, to explain and describe the characteristics of the solutions with sharp gradients, to create models with stable solutions and thereby to simplify the numerical analysis. …”
