Experimental investigation of condensation heat transfer on hybrid wettability finned tube with large amount of noncondensable gas

Condensation heat transfer outside horizontal plain and finned tubes with different surface wettability is experimentally studied. The methods of self-assembled monolayer coatings of n-octadecyl mercaptan with oxidation and etching treatments are employed to create the hydrophobic surfaces or superh...
