Time-periodic Poiseuille-type solution with minimally regular flow rate
Nonlinear Analysis, 2021 The nonstationary Navier–Stokes equations are studied in the infinite cylinder Π = {x = (x', xn) ∈ Rn: x' ∈ σ ∈ R n – 1: – ∞ < xn < ∞, n = 2, 3} under the additional condition of the prescribed time-periodic flow-rate (flux) F(t). It is assumed that the

Non-stationary Navier–Stokes equations in 2D power cusp domain
Advances in Nonlinear Analysis, 2021 The initial boundary value problem for the non-stationary Navier-Stokes equations is studied in 2D bounded domain with a power cusp singular point O on the boundary. The case of the boundary value with a nonzero flow rate is considered.

Boundary Value Problems, 2020 In this work, we propose a nonstationary Navier–Stokes problem equipped with an unusual boundary condition. The time discretization of such a problem is based on the backward Euler’s scheme.

Dirichlet problems for a nonstationary linearized system of Navier–Stokes equations in non-cylindrical domains [PDF]
Methods and Applications of Analysis, 2002 The authors consider \(L_2\)-boundary value problems for the instationary Stokes system over non-smooth time-varying infinite cylinders. Results on solvability, uniqueness, and regularity are obtained for Dirichlet and Neumann type boundary conditions via the study of parabolic layer potentials.

A nonoverlapping DDM for the nonstationary Navier‐Stokes problem
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001 AbstractWe consider the nonstationary incompressible Navier‐Stokes problem in a bounded domain. A semidiscretization in time followed by a linearization procedure lead to Oseen type problems. For an efficient solution we take advantage of a nonoverlapping domain decomposition method (DDM) with interface conditions of Robin type.

Free boundary problems for nonstationary Navier–Stokes equations [PDF]
Dissertationes Mathematicae, 2004 The paper contains a detailed survey of nonstationary free boundary problems for equations of motion of both incompressible and compressible viscous fluids for the last twenty years. The following two problems are considered. The first is the problem of describing the motion of an isolated mass of a viscous fluid bounded by a free surface.
