Abstract:
The paper presents a new class of exact solutions for the Navier–Stokes
equations. These solutions describe unsteady three-dimensional in velocities
and two-dimensional in coordinates for a viscous incompressible fluid flow.
The procedure for constructing an exact solution generalizes Trkal's method
proposed for studying screw flows. The new class of exact solutions allows
to describe non-hecical flows (the velocity vector forms a nonzero angle
with the vorticity vector) and fluid flows existing in a finite time.
Keywords:
Navier-Stokes equation, exact solution, Trkal's method, eigenfunctions of the Laplacian, non-helical flows, blow-up regimes.
