“…To check the chemical kinetics of the skeletal mechanism, the global reaction path analysis by employing the element flux analysis method is used, which is only briefly outlined. Generally, the element flux for an element (such as C) from species k 1 to k 2 at instantaneous time t is calculated via where , , and N E , i are the number of atom E in species k 1 , species k 2 , and reaction i , respectively. The global element flux during ignition simulations can be derived via time‐integrated method as Subsequently, the normalized weight of element flux from k 1 to k 2 to the total out flux of species k 1 can be easily derived as …”
