High Turbulence Corrosion Loop (HTCL) Flow Testing for Characterization of Nanostructured Nickel-Copper (Ni-Cu) Electrodeposited Materials
Abstract
Shipboard heat exchanger tubes are typically constructed of 90/10 CuNi alloy which is prone to erosion corrosion and abrasion thin walling, leading to eventual failure. This failure mode places equipment and ship operational availability at risk from cross-contamination with sea water or reduces thermal exchange efficiency when defective tubes must be plugged. Cost of removal/refit and/or replacement is an expensive maintenance requirement. At full maturity, it is anticipated that an in-situ repair capability will obviate the need to replace tube bundles. The ONR Tech Candidate program, supported by the Virginia Tech team, will provide the necessary" technology maturation for the FY20 FNC entitled, ""Navy Heat Exchanger Amelioration Tool (N-HEAT)The Virginia Tech (VT) High Turbu"lence Corrosion Loop (HTCL) facility possesses the laboratory capability and instrumentation necessary to conduct and record behavior of multiple test specimens concurrently in a parallel environment. Testing several series of specimens in a controlled, simulated environment supports generation of statistically significant turbulent flow performance data for this novel technology.
