To evaluate the effect of hydrogen fraction and equivalence ratio on the competitive relationship between flame and crack development, combustion experiments of H2/CO/air mixtures at various equivalence ratios and hydrogen fractions were conducted in a constant volume combustion chamber. The crack length and growth rate were defined. The results indicate that the crack length and the number of the...
The present work experimentally studies the correlation between the cellular structure of a flame front and the pressure of methane/hydrogen/air laminar premixed flame at various equivalence ratios and hydrogen fractions in a spherical combustion chamber. The effects of the equivalence ratio and the hydrogen fraction on the explosion characteristics and evolution of the cellular structure of the flame...
The phenomenon of shock waves can be commonly seen in fuel spray under ultra-high injection pressure conditions, where the spray jet penetrates at speeds greater than Mach 1. This paper focuses on the induction of shock waves and their propagation characteristics generated by a supersonic fuel jet at 400MPa, and simultaneously considers the impact of jet atomization. A specially designed atomizer,...
