Towards understanding the algorithms for solving the Navier–Stokes equations

In this paper, we proceed exploring the case of non-stationary helical flows Navier-Stokes equations for incompressible fluids with variable (spatially dependent) coefficient proportionality between velocity and curl field flow. Meanwhile, system (including continuity equation) has been successfully explored previously respect to existence analytical way presentation aforementioned type. The main motivation current research is stability obtained flows. Conditions criteria exact solution type are obtained, which flow invariant Bernoulli-function considered. As it formulated before, spatial part pressure fluid should be determined via Bernoulli-function, if components already obtained.
