Modeling a run-around heat and moisture exchanger
using two counter/cross flow exchangers.
Although the configuration of the heat and moisture exchanger
investigated in this paper (i.e., a moving porous bed exchanging heat and moisture with air flowing in a cross-flow direction) is very different from heat-and-moisture transfer in a rotating energy wheel, there are many similarities in the basic governing equations.

These HMEs (heat and moisture exchangers
) act as an artificial nose and regain some of the lost respiratory functions of the nose for persons breathing through a tracheostoma.
