As is evident, in the presence of chemical reactions, the analysis of the topic in question becomes more complex. Therefore, in this work, only an exploratory approach is carried out, based on scale analysis. Thus, based on the model assumptions and the scales in Table , it can be said that the present model -to lumped parameters in both phases -is more suitable for systems with negligible mass transfer effects, and small Bi, Da ef and Th M , respectively. The choice of small values for these dimensionless numbers make the conduction scale 𝑡 ? (see Table ) considerably smaller than the other particle phenomena scales. However, it is understood that this may be a very conservative criterion and therefore an initial assessment is carried out in the next section.
