Investigation of flow next to membrane walls
TL;DR: In this paper, a flat membrane demo-model demonstrating flow through the spacer between two membranes was used to measure velocity and estimate the magnitude of mixing index (MI) within a unit cell of the turbulence promoter net.

An experimental and theoretical analysis of turbulence promoter assisted ultrafiltration of synthetic fruit juice
TL;DR: In this article, an organic ultrafiltration membrane (PPE 30, poly phenylene ethersulfone) of 30 k molecular weight cut off was used for continuous cross flow mode with an organic ultrafiltration membrane.

A model for the screen-printing of Newtonian fluids
TL;DR: In this article, a mathematical model for the printing of a thin film of Newtonian fluid was proposed, in which the screen is modelled as a permeable membrane, and the entire region above and below the screen was flooded.

Numerical modeling of anisotropic drag for a perforated plate with cylindrical holes
Young Min Bae,Young In Kim +1 more
TL;DR: In this paper, direct numerical simulations of an incompressible laminar flow past a perforated plate are carried out at the pore scale, with the aim of evaluating the anisotropic drag of a perfused plate, and two simple flow tests have been conducted: i) transpiration flow through a porosity of 0.1-0.4 and hole depth to diameter ratios of 1-3 at pore level Reynolds numbers of up to 25.

Boundary conditions at a naturally permeable wall
TL;DR: In this article, a simple theory based on replacing the effect of the boundary layer with a slip velocity proportional to the exterior velocity gradient is proposed and shown to be in reasonable agreement with experimental results.

On the Boundary Condition at the Surface of a Porous Medium
P. G. Saffman,P. G. Saffman +1 more
TL;DR: In this paper, a theoretical justification for an empirical boundary condition proposed by Beavers and Joseph is given for non-homogeneous porous medium, and the statistical approach is checked by using it to derive Einstein's law for the viscosity of dilute suspensions.

Dynamics of a fluid interface Equation of motion for Newtonian surface fluids
TL;DR: In this article, the authors derived a completely general formulation of the dynamics of a Newtonian fluid interface, that is, one whose rheological behaviour is characterized by its equilibrium interfacial tension and B oussinesq's [18] two coefficients of surface viscosity.
Book
Mechanics and Thermodynamics of Biomembranes
TL;DR: One of the most exciting and rapidly growing areas of research in cell biology today is the structure and function (mechanical and chemical) of cell membranes, and this book by Drs Evans and Skalak is a very welcome and much needed addition to the field.
