Progress is reported in this project to evaluate benefits associated with control of the surface energetic properties of materials used in heat exchangers; and to identify preferred ranges of these surface conditions that minimize deposits of biological fouling known to deteriorate heat exchange efficiencies in seawater, brackish water, and freshwater systems. The technical approach uses special diagnostic plates in novel flow cells where fluid flow conditions can be well-controlled, modifying the surface chemistry and surface energy of the plates with very thin coatings and examining the earliest events of biofouling caused by macromolecules and microbial organisms. A preliminary list of test surfaces is given. Initial progress was made for measuring heat exchange coefficients using germanium internal reflection plates. A coastal marine aquarium system was established to simulate real-world biofouling conditions.
