Progress on Dropwise Condensation Mechanismand Heat Transfer Surface Modification

A review of dropwise condensation mechanism and heat transfer surface modification was presented. The droplets and film coexisting condensation mechanism was the reasonable one by contrast. The plasma technique had a potential application in modifying solid surface to promote dropwise condensation. The further study should focus on the determination of the best technological conditions of the plasma surface modification based on the organic vapor dropwise condensation and introduction of molecular self-assembled, nanometer and bionics technology to the field of condensation surface modification.
