Effect of the reactor model on steady detonation modeling

The effect of employing four different reactor models, Zeldovich–von Neumann–Döring (ZND), constant volume (CV), pressure (CP), and the Shock routine from Chemkin, to perform detonation-relevant chemical modeling was assessed. simulation results were compared in terms characteristic length scales analyses with representative mixtures: $$\hbox {H}_{2}{-}\hbox {O}_{2}{-}\hbox {N}_{2}$$ , {NO}_{2}/{\hbox {N}_{2}}{\hbox {O}_{4}}$$ $${\hbox {C}_{3}}{\hbox {H}_{8}}{-}\hbox dimethyl ether (DME)– {CO}_{2}$$ . following conclusions drawn: (i) CV CP models shorten induction zone strengthen energy release rate most mixtures. In kinetics, impact is quite limited for However, C2 branch enhanced mixture. Moreover, both weaken intermediate-temperature chemistry promote high-temperature DME– mixtures; (ii) module can be employed detonation modeling, as it provided similar ZND simulations all investigated (iii) model preferred over zero-dimensional while ANSYS equivalent reactor.
