Molecular dynamics simulations of reactive neutral chemistry in an argon‐methane plasma

Résumé

Molecular dynamics simulations are performed to study the reactions in the volume of a low-pressure methane plasma diluted in argon. In the first step, a 1D fluid model is used to determine the initial molar fractions of initial species. The obtained composition thus becomes the input for the reactive molecular dynamics simulations. The study is carried out at 300, 400, 500, and 1000 K. Increasing the temperature increases the range of different molecules formed. The time evolution of C 2 H and CH 3 and the different reaction pathways leading to larger molecules show that C 2 H is the main precursor and CH 3 is the main intermediate precursor for the formation of large molecules.
