The problem of heat and mass transfer within a porous catalytic pellet in which an irreversible first-order exothermic reaction occurs is a much-studied problem in chemical-reactor engineering. The ...

Reaction-diffusion systems represent a fundamental mathematical framework to model the interplay between local reactive processes and diffusive transport of substances. These systems have wide-ranging ...

The analytic solution of the diffusion equation in finite domains, when time and space is continuous, has been known for a long time. “However, to compare model predictions with empirical observations ...
