Fluids in the environment and technological apparatuses are stratified due to inhomogeneity of pressure, temperature or concentrations of dissolved substances or suspended matter. Observations have shown that even small variations of density create new phenomena, which are absent in a homogeneous fluid, like diffusion induced flows, multicomponent convection and internal waves. Stratification impacts dramatically on flows dynamics and structure as well as transport of matter, momentum and energy. Stratified flows are traditionally observed in atmosphere and hydrosphere and modelled basing on different theoretical approaches including theories of turbulence, boundary layers, vortex flows and linear waves. The goal of the session is to collect talk concerning stratified flow phenomena observations and modelling and to discuss consistency of different models.
