The Time of Synchronization of Oscillationsin Two Coupled Identical   Subsystems
  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.
