Innovative Material (and Application Method) for a Hydrophobic/Oleophobic Coating to an Aluminum-Bodied Heat Exchanger TxHiEnergy

The overall objective of the proposed Phase II Base work is to demonstrate the capabilities of a full-size coated heat exchanger in a high-fidelity simulated operational environment. The test data from Phase II is intended to be sufficient for approval of flight qualifications. Specifically, the coating application method will be demonstrated on a full-size heat exchanger assembly; and the heat transfer, erosion, and fouling resistance will be demonstrated on one of the heat exchanger cores from the full assembly across the entire operating temperature range. The fouling deposition protocol will involve an oil mist or vapor designed to closely simulate the fouling mechanisms encountered in an operational environment.
