Comparative assessment of the linear driving force and pseudo-gas-side-controlled models for the prediction of mass transfer in desiccant matrices

Simplified and realistic simulation models are of great relevance for industrial development of components and systems. The simplified approaches based on the pseudo-gas-side-controlled model and on the linear driving force model are investigated in the simulation of the mass transfer phenomena between the airflow and the channel wall of a solid desiccant matrix. The differences between the two approaches lie in the mass transfer coefficient and potential that are considered in the conceptual equation.
