          <datacite:description descriptionType="Other">The generation of the turbulent secondary flow in a rectangular duct is investigated in the framework of hydrodynamical nonlinear instability of the corresponding laminar flow. The secondary flow is obtained as an equilibrium state of growing unstable disturbances.</datacite:description>
