Abstract

This paper analyzes the main sources of exergy destruction during the non-equilibrium combustion of the hydrogen-natural gas engine. The performance of five representative CH

kinetic models in the literature is re-evaluated and a method for calculating exergy destruction of elementary reactions is preliminarily established based on non-equilibrium thermodynamics. Combined with the selected kinetic model

the exergy destr

uction behaviors during the auto-ignition of CH

mixtures under different initial conditions(temperatures

equivalence ratios

hydrogen ratios)are numerically analyzed. According to the results

with the initial temperature increases

exergy destruction caused by chemical reaction decreases

while exergy destruction from incomplete combustion increases. Moreover

addition shows little effect on the total exergy destruction

but effectively extends the low exergy destruction zone of CH

combustion. The time histories of exergy destruction at different temperatures and varied H

additions are compared; the rates of production(ROP)of H(·overO)

and(·overO)H radicals

as well as the contribution of the elementary reactions that dominate their generation and consumption to the exergy destruction

are analyzed

to reveal the effects of initial temperature and H

addition on exergy destruction of CH

combustion. Furthermore

the discrepancy in exergy destruction between CH

high-/low-temperature oxidation pathways is thermodynamically clarified by comparing the Gibbs free energy of key species during fuel oxidation. The research results reveal the effects of H

addition on exergy destruction during CH

combustion at molecular reaction level

and is expected to provide theoretical guidance for further reducing exergy destruction of hydrogen-natural gas engine combustion.
