In this paper, a new approximate solution of time-fractional order multi-dimensional Navier–Stokes equation is obtained by adopting a semi-analytical scheme: “Fractional Reduced Differential Transformation Method (FRDTM)”. Three test problems a

We consider the zero viscosity limit of the incompressible Navier–Stokes equations with non-slip boundary condition in R + 3 for the initial vorticity located away from the boundary. Unlike 2-D case, this kind of data is not analytic in ( x , y ) f

In this paper, we mainly study the existence of self-similar solutions of stationary Navier–Stokes equations for dimension n = 3 , 4 . For n = 3 , if the external force is axisymmetric, scaling invariant, C 1 , α continuous away from the origin an

We investigate the existence, uniqueness and stability of bounded and almost periodic mild solutions to several Navier–Stokes flow problems. In our strategy, we propose a general framework for studying the semi-linear evolution equations with certa

In this paper, we consider a regular grid with equal spatial spacings and construct a new finite difference approximation (difference scheme) for the system of two-dimensional Navier–Stokes equations describing the unsteady motion of an incompressi

In this contribution, we review classical mixed methods for the incompressible Navier–Stokes equations that relax the divergence constraint and are discretely inf-sup stable. Though the relaxation of the divergence constraint was claimed to be harm

In this paper, we investigate the partial regularity of suitable weak solutions to the multi-dimensional stationary Navier–Stokes equations with fractional power of the Laplacian (−Δ) α (n/6 ≤ α < 1 and α ≠ 1/2). It is shown that the n +

The paper is devoted to a theoretical analysis of a counter-current gas-liquid flow between two inclined plates. We linearized the Navier–Stokes equations and carried out a stability analysis of the basic steady-state solution over a wide variation

Two-step algorithms for the stationary incompressible Navier–Stokes equations with friction boundary conditions are considered in this paper. Our algorithms consist of solving one Navier–Stokes variational inequality problem used the linear equal
