![]() ![]() The present workĭemonstrates the important role of the kinetic model in the simulation Trend of the convective heat transfer coefficient. Of fluid to the average specific heat, can well reflect the changing Of isobaric specific heat, which is the ratio of the specific heat The several influencing factors of heat transfer, the correction factor Of the fuel, which in turn affects the convective heat transfer. In addition, pyrolysis affects the properties Temperature, which in turn affects the reaction rate and finally theĬonversion of the fuel. Product distribution affects the chemical endotherm and then the fuel It mainly cracked into large molecules even at high conversion. The new model generates more products of small molecules due to theĬonsideration of secondary reactions. Simulation are analyzed from the perspective of chemical kinetics. Reasons for the difference of the two chemistry models in the CFD Show that the high-accuracy model is more accurate in terms of fuelĬonversion, temperature, and product distribution. Results of a one-step global model as the chemistry model. Of the supercritical cracking heat transfer, and compared with the Model is applied to the computational fluid dynamics (CFD) simulation Has high accuracy in predicting species distribution. One-dimensional plug flow reactor simulation verifies that the model Reaction model of n-decane containing 16 species and 26 reactions. Reaction at high conversion, the present work establishes a cracking Mechanism models of n-decane, and considering the impact of the secondary Endothermic hydrocarbon fuel plays a vital role ![]()
