ADVANCED MATERIALS AND DEVICES
This Small Business Technology Transfer Research (STTR) Phase II project seeks to develop and commercialize an optimized technique to produce durable nano-porous surfaces (NPS) for heat transfer applications using an inexpensive electrochemical process. This technology will be very beneficial for the development of high-efficiency boilers, heat exchangers and electronic cooling devices. The objectives for Phase II will be
1) To further examine the aging effect in heat transfer performance. Nano-porous layers with different size and thicknesses will be employed in boiling heat transfer experiments to find the optimum size and thickness of the layer that would maximize the life of the surface without compromising the enhancement in heat transfer rate.
2) To develop a scale-up process for the production of NPS by varying the anodization process parameters, such as electrolytic concentration, applied potential or current densities, and temperature of the electrolyte.
3) To evaluate the stability and durability of NPS utilizing a modified OEM boiler. A commercially available boiler will be modified and retrofitted with the proposed NPS to examine its stability and durability.
The broader impact/commercial potential of this project will be the enhancement to boilers, heat exchangers, and electronic cooling devices that serve various industries, such as, power/utility, oil and gas, chemical, food and beverage, and building and construction. Additional benefit from the this project will be its potential application in efficient heat transfer to increase energy output, reduce energy consumption and greenhouse gases, consume less fossil fuels and reduce harmful pollution.
