Modeling of vibrational non-equilibrium in detonation with global kinetics

One-, two-, and three-step global kinetic models that include thermal non-equilibrium were developed for detonation simulations using the open-source software Cantera and the Shock and Detonation Toolbox (SDToolbox). The rate coefficients and thermodynamic parameters of these mod...

Controlling high-temperature exposure and product selectivity in pulsed microwave plasma methane coupling

Plasma can couple methane to higher hydrocarbons thereby providing opportunities for carbon circularity. Efficiency and control over ethylene and acetylene selectivity versus undesired soot formation are keys to success and the result of a delicate balance between reactor tempera...
