for large and complex reacting systems, computational efficiency becomes a critical issue in process simulation, optimization and model-based control. mechanism simplification is often a necessity to improve computational speed. we present a novel approach to simplification of reaction networks that formulates the model reduction problem as an optimization problem and solves it using genetic al...

A simplified reaction mechanism for propane combustion has been derived. This scheme is based on two competitive fuel decomposition reactions. Further, the combustion of hydrogen has been used to derive the concentrations of the intermediate reactive species, and the kinetic parameters for the rate equations are estimated through comparison of the species concentrations calculated using detaile...

Typically, Sn cannot be finished on Ni and Ag surfaces via the immersion process. In this work, through galvanic reaction, finish was processed an coexisting with a surface. Herein, detailed mechanism of reduction Sn2+ ions surface reaction is reported. Through transmission electron microscopy X-ray diffraction analysis, uncommon Ag4Sn phase, instead common Ag3Sn confirmed to form during layer....

In this paper, the applicability of the entropy method for the trend towards equilibrium for reaction-diffusion systems arising from first order chemical reaction networks is studied. In particular, we present a suitable entropy structure for weakly reversible reaction networks without detail balance condition. We show by deriving an entropy-entropy dissipation estimate that for any weakly reve...
