A criterion based on the computational singular perturbation (CSP) method is proposed in order to determine the number of quasi-steady state (QSS) species. This criterion is employed for the reduction of a detailed chemical kinetics mechanism for the oxidation of dimethyl ether (DME). involving 55 species and 290 reactions. leading to a 20 steps reduced mechanism which involves 26 spe... https://jalyttlers.shop/product-category/espresso-maker/
