The heat transfer and pressure drop characteristics of moist air in metal foam during the flow and dehumidification process were investigated experimentally

and the influence of different factors was analyzed. Heat transfer rate and pressure drop increased with increasing relative humidity as a result of increasing condensate water. When relative humidity increased from 50% to 90%

heat transfer and pressure drop respectively increased by 67% and 62%. With the increase of inlet air temperature

heat transfer rate and pressure drop increased. Heat transfer rate and pressure drop decreased with increasing cooling water temperature

pressure drop increased with increasing pore density

while heat transfer at first decreased slightly and then increased because of the influence of condensate water. Heat transfer rate and pressure drop increased with the increase of windward height of copper foam.
