Regularity of spots chain dynamics with intervals

The task of the spots chain dynamics with initial intervals of mixed liquid in stratified environment, and viscous flow is considered. To solve the problem, the splitting method for studying incompressible fluid flows (SMIF method) is used. The finite-different scheme of SMIF has such properties as the second order of approximation on spatial variables, minimal scheme dissipation and dispersion. The results of the formation of a streak depending on the Reynolds and Froude numbers values and the initial interval between spots are presented. Two characteristic variants were identified among the calculating variants. There are four stages of horizontal banding dynamics of spots chain with intervals.
