Low-order dynamical models for vortical flows of inviscid fluid in square area
Autors:
Petrovskaja Natalja Vladimirovna, Southern Federal University
Abstract:
The Galerkin method together with the method of small parameter is applied for study of Routh-like equations describing the dynamics of two-dimensional inviscid incompressible fluid flows. A set of simple models for some vortical flows of such fluid in rectangular area has been derived and analysed.
