Non-Stationary Helical Flows for Incompressible Couple Stress Fluid [PDF]

Mathematics, 2023
We explored here the case of three-dimensional non-stationary flows of helical type for the incompressible couple stress fluid with given Bernoulli-function in the whole space (the Cauchy problem).

On a new type of non-stationary helical flows for incompressible 3D Navier-Stokes equations

Journal of King Saud University - Science, 2020
Abstract In fluid mechanics, a lot of authors have been executing their researches to obtain the analytical solutions of Navier-Stokes equations. But there is an essential deficiency of non-stationary solutions indeed. In our presentation, we proceed exploring the case of non-stationary helical flows of the Navier-Stokes equations for ...

Numerical study of dynamical system generated by CABC vector field [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика, 2020
Purpose of this study is to construct a helical vector field and analyze the dynamical system generated by it. Classic example of such field is the ABC (Arnold–Beltrami–Childress) flow, which is equations stationary solution of the dynamics of ideal ...

Anisotropic Wave Turbulence for Reduced Hydrodynamics with Rotationally Constrained Slow Inertial Waves

Fluids, 2017
Kinetic equations for rapidly rotating flows are developed in this paper using multiple scales perturbation theory. The governing equations are an asymptotically reduced set of equations that are derived from the incompressible Navier-Stokes equations ...
