Efficient methods for solving the Stokes problem with a friction effect simulated by the slip boundary condition are developed. The dual formulation of the problem arising from the finite element approximation leads to the minimization of the strictly quadratic function with few unknowns constrained by simple bounds.

International Journal for Numerical Methods in Fluids, 1984
AbstractA family of simple Stokes flows involving sliding surfaces adjacent to surfaces at rest is considered. Principally, two specific flow configurations are investigated: (i) that arising when parts of the boundary of an infinitely long circular cylinder are rotating about the axis while other parts of the boundary are at rest, and (ii) the flow ...

Stokes flow in a rectangular cavity with a cylinder
Fluid Dynamics Research, 1999Summary: The Stokes flow in a rectangular cavity with two opposite fixed and two opposite moving walls and a (rotating) cylinder in the centre is investigated. This flow is used as a prototype flow for studying distributive mixing. A general analytical method of superposition is implemented.

Stokes Flow Around a Rolling Cylinder
ASME 2010 8th International Conference on Nanochannels, Microchannels, and Minichannels: Parts A and B, 2010Micropumps are a necessary device for microfluidics. Many solutions are possible and technical devices are numerous. In this paper, we have developed an analytical solution for the peristaltic technique in microchannels that enlighten some physical limitations.

Comparison between Newtonian fluid flow, Stokes flow and Stokes-Oseen flow
International Journal of Multidisciplinary Research and Growth EvaluationViscosity is an intrinsic property of fluids. It originates in the thermal interactions of molecular collisions. There are two types of it: kinematic viscosity and dynamic viscosity. In this work, we try to model the flow of viscous fluid in three cases: Newtonian fluid flow, Stokes flow and the Stokes-Oseen flow.

On the Representation of Stokes Flows
SIAM Journal on Mathematical Analysis, 1991In this paper representations of Stokes flows in dimensions 2 and 3, which reduce the Stokes equations to the Laplace equation for an auxiliary function, are given. While it is known that two- and three-dimensional Stokes flows may be reduced to biharmonic problems, the representations here are new. The main result of this paper reads as follows: Given

Unsteady Stokes Flow in a Distensible Pipe
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1991AbstractIn this paper the solution is presented of the problem of unsteady Stokes flow in a semi‐infinite distensible pipe, with initial conditions given at the pipe inlet. The solution is obtained through an eigenfunction expansion, utilizing Van Kampen's method for the determination of the expansion coefficients. In this way a complete description is
