Abstract:

The effects of hydrodynamic variables on the corrosion rate of 9010 Cu-Ni were studied in sea water pumped from Monterey Bay. A one centimeter square flow channel was built providing a maximum flow velocity of 7.8 msec. The flow field was examined using hot film anemometry in an attempt to correlate variables such as turbulence intensity to corrosion rate. General concepts of turbulence that may affect corrosion are discussed with a view toward resolving the disparities in reported corrosion data taken under different flow situations. Possible leading edge effects due to the establishment of the mass transfer boundary layer were investigated and found to be negligible in 48 hour tests, provided care was taken to avoid crevices or mismatches in the channel wall.
