HEAT EXCHANGER SYSTEM AND METHOD OF OPERATION
A method of operating a heat exchanger (10; 20) is disclosed in which an electric field is applied to a hydrophobic surface having condensed water droplets (302) thereon to reduce a contact angle (¸) between the individual droplet surfaces and the hydrophobic surface, and to increase droplet surface energy (E) to a second surface energy level. The electric field is removed to increase the contact angle between the individual droplet surfaces and the hydrophobic surface, and to reduce droplet surface energy to a third surface energy level. The third surface energy level is greater than the first surface energy level and greater than a surface energy level for a free droplet. A portion of the droplet surface energy is converted to kinetic energy to detach droplets from the hydrophobic surface. The detached droplets are removed from the heat rejection side fluid flow path.
