چکیده

The paper announces a family of exact solutions to Navier–Stokes equations describing gradient inhomogeneous unidirectional fluid motions (nonuniform Poiseuille flows). structure the motion is such that incompressibility equation enables us establish velocity defect law for nonuniform flow. In this case, field dependent on two coordinates and time, it an arbitrary-degree polynomial relative horizontal (longitudinal) coordinate. coefficients depend vertical (transverse) coordinate time. solution under consideration was built using method indefinite use algebraic operations addition multiplication. As result, determine coefficients, we derived system simplest homogeneous parabolic partial equations. order integration resulting recurrent. For special case steady flows viscous fluid, these are ordinary differential article presents algorithm their integration. all components field, vorticity vector, shear stress functions. addition, has been noted even without taking into account thermohaline convection (creeping current) fields have rather complex structure.

Effective equations describing the flow of a viscous incompressible fluid through and tangentially to a filter

We study the 2D creeping flow of a viscous incompressible fluid through and tangentially to a thin filter. The flow is governed by given pressure drops in horizontal and vertical directions. Filter consists of periodically placed perforations of the typical size . The filter thickness is of the same order. By employing the boundary layer technique due to W. Jäger and A. Mikelić, we obtain the e...

Exact N - vortex solutions to the Ginzburg - Landau equations for κ = 1 / √ 2

The N-vortex solutions to the two-dimensional Ginzburg-Landau equations for the κ = 1/ √ 2 parameter are built. The exact solutions are derived for the vortices with large numbers of the magnetic flux quanta. The size of vortex core is supposed to be much greater than the magnetic field penetration depth. In this limiting case the problem is reduced to the determination of vortex core shape. Th...
