Effect of Non-Condensable gas on condensing performance of HFE7100 With/Without hydrophobic coating

Intrinsic Water Transport in Moisture-Capturing Hydrogels

“…During desorption, the bulk convection has an opposite direction and carries away both water molecules and NCGs, preventing NCG accumulation near the surface (Figure f). These observations are consistent with previous experiments of evaporation and condensation in pure-vapor environments − and explain their prominent effect during absorption of the porous samples. The nonporous samples do not exhibit differences in absorption and desorption kinetics, as it is easier for NCGs to diffuse away from the flat surface.…”
