Enthalpy distribution at the front of an one-dimensional laminar flame

详细

The enthalpy distribution at the front of one-dimensional flames of homogeneous mixtures of hydrogen, propane, formaldehyde, and methanol with air was numerically investigated. It is shown that the enthalpy distribution is more complex than the classical concepts: the enthalpy can both increase and decrease relative to the initial value. The specific form of the distribution is determined, in particular, by intermediate components formed at the flame front as they are also carriers of chemical energy and transfer it due to diffusion.
