Wavy Wake Formation in the Absence of Submerged Bodies in Electrolyzed Salt Water

抄録

It has been found experimentally that in electrolyzed salt water, a wavy wake forms in the absence of submerged bodies downstream of a localized region influenced by the magnetic field of permanent magnets moving at a constant velocity. The lower and upper critical numbers of a dimensionless current density (Q) for the formation region of the wavy wakes decrease with Reynolds number. A straight wake and a meandering wake also form at smaller and larger values of Q, respectively. No wake formation of this type occurs in nonelectrolytic common fluids.
