摘要
An external force field can alter the structure of a flow by the generation of spatial nonuniformity and fluctuating motions. In particular, the spatial nonuniformity of the buoyant forces in stratified shear flows results in the generation of vortices, whose axes have a definite orientation relative to the gravitational forces. One of the best-known examples of this situation is the phenomenon of the circulation of mediterranean sea water in the Atlantic Ocean. A mathematical model is used to investigate the specific characteristics of the turbulent structure of unsteady plane-parallel flow of a three-layer fluid.
