Chemical dynamics simulations of energy transfer in CH 4 and N 2 collisions.

Chemical dynamics simulations have been performed to study the energy transfer from a hot N 2 bath at 1000 K to CH 4 fuel at 300 K at different bath densities ranging from 1000 kg m -3 to 30 kg m -3 . At higher bath densities, the energy transfer from the bath to the fuel was rapid and as the density was decreased, the energy transfer rate constant decreased. The results show that in combustion systems with CH 4 as a prototype fuel, the super pressure regimes control the fuel heating and combustion processes.
