N2 - A mathematical model based on the one-dimensional Navier-Stokes equation is described. The current model is capable of predicting the transient and steady-state transport in a desiccant wheel. It reveals the moisture and temperature in both the airflow channels and the sorbent felt, in detail, as a function of time. The predicted results are validated against the data taken from experimental results, with reasonable accuracy. Therefore, the numerical model is a practical tool for understanding and accounting for the complicated coupled operational process inside the wheel. Consequently, it is useful for parameter studies. As a demonstration of its utility, the model is employed to study the effect of felt thickness and passage shape on the performance of a desiccant wheel.
