Predicting the Air-Side Thermal -Hydraulic Performance Characteristics of Flat-Tube Louver-Fin Heat Exchangers Under Dry and Wet Conditions
… numerical methods. When condensate obstructs the louver gap, boundary layer re-starting does not occur, and the most important heat transfer enhancement mechanism in these flows lost. It is shown that surface tension can maintain inter-louver condensate bridges against gravity and flow-generated …

Air-side condensate management: Drainage channels in heat exchangers
… retention characteristics of compact flat-tube louver-fin heat exchangers is presented. Various geometries of drainage channels are engraved on surrogate tubes in contact with fin stock. Two fin designs are tested using a dynamic dip testing method, and four designs are tested in a small wind …

Experimental study of the thermal-hydraulic performance of a brazed aluminum heat exchanger under wet-surface conditions
… The test specimen is a brazed-aluminum, louvered-fin heat exchanger. The total capacity, pressure drop and water drainage behavior under various water usage rates and air face velocities are explored and compared to data from dry-surface conditions. The impact of spray orientation is also …
