Biofouling and cleaning experiments for OTEC heat exchangers

Technical Report ·
OSTI ID:6927569

In the Applied Physics Laboratory (APL) Ocean Thermal Energy Conversion (OTEC) plant-ship concept, large-diameter (3-in.) aluminum tubes with ammonia flowing inside are being proposed for use as low-cost multipass heat exchangers. Experiments to measure the rate of biofouling and its effect on exterior heat transfer have been conducted by APL at the Natural Energy Laboratory of Hawaii, Ke-Ahole Point, Hawaii. The results are directly applicable to the design of the APL heat exchanger.
