  The mechanism of synchronization of oscillations in two identical coupled
flow systems has beenstudied. The time (past the coupling onset) during which a
synchronous oscillation regime is establisheddepends on the oscillation phase
difference between the subsystems. Variation of the coupling parameter leadsto
a change in the character of dependence of the synchronization time on the
phase difference. Several typesof synchronization processes are revealed, which
are realized for various values of the coupling parameter.
