Numerical Investigation into CO2 Emission, O2 Depletion, and Thermal Decomposition in a Reacting Slab

الملخص EN

The emission of carbon dioxide (CO2) is closely associated with oxygen (O2) depletion, and thermal decomposition in a reacting stockpile of combustible materials like fossil fuels (e.g., coal, oil, and natural gas).

Moreover, it is understood that proper assessment of the emission levels provides a crucial reference point for other assessment tools like climate change indicators and mitigation strategies.

In this paper, a nonlinear mathematical model for estimating the CO2 emission, O2 depletion, and thermal stability of a reacting slab is presented and tackled numerically using a semi-implicit finite-difference scheme.

It is assumed that the slab surface is subjected to a symmetrical convective heat and mass exchange with the ambient.

Both numerical and graphical results are presented and discussed quantitatively with respect to various parameters embedded in the problem.
