Abstract
The effects of hydrodynamic variables on the corrosion
rate of 90/10 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 m/sec. 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.
