Enhanced dip coating on a soft substrate

A solid, withdrawn from a wetting liquid bath, entrains a thin liquid film. This simple process, first described by Landau, Levich, and Derjaguin (LLD), is commonly observed in everyday life. It also

Evaporation of liquid coating a fiber

We investigate theoretically and numerically the diffusion-limited evaporation of a liquid deposited on a fiber in two configurations: a sleeve and an axisymmetric barrel-shaped droplet. For a

Dip-coating of suspensions.

This article studies the Landau-Levich problem in the case of a suspension of non-Brownian particles at moderate volume fraction 10% < φ < 41%.

Entrainment of particles during the withdrawal of a fibre from a dilute suspension

Abstract A fibre withdrawn from a bath of a dilute particulate suspension exhibits different coating regimes depending on the physical properties of the fluid, the withdrawal speed, the particle

Dip-coating flow in the presence of two immiscible liquids

Abstract Dip coating is a common technique used to cover a solid surface with a thin liquid film, the thickness of which was successfully predicted by the theory developed in the 1940s by Landau &

The Thickness and Structure of Dip-Coated Polymer Films in the Liquid and Solid States

Films formed by dip coating brass wires with dilute and semi-dilute solutions of polyvinyl butyral in benzyl alcohol were studied in their liquid and solid states. While dilute and semi-dilute

Triple line destabilization: Tuning film thickness through meniscus curvature

For partially wetting fluids, previous results suggest that the thickness and the dewetting velocity of gravity driven films are uniquely determined by the triple line dynamics. In contrast, when

Particulate suspension coating of capillary tubes.

The displacement of a suspension of particles by an immiscible fluid in a capillary tube or in porous media is a canonical configuration that finds application in a large number of natural and

Dip coating of bidisperse particulate suspensions

Abstract Dip coating consists of withdrawing a substrate from a bath to coat it with a thin liquid layer. This process is well understood for homogeneous fluids, but heterogeneities, such as



Liquid coating from a surfactant solution

A solid drawn out of a pure wetting liquid comes out coated with a layer of liquid, of thickness given by the Landau equation (for small coating velocities). If the solid is drawn from a solution

Thick films of viscous fluid coating a plate withdrawn from a liquid reservoir.

The phase diagram for the existence of stationary film solutions as well as the film profiles are calculated and find excellent agreement with experiment.


▪ Abstract We discuss the thickness of the liquid layer entrained by a solid drawn out of a bath, focusing on the case where the solid is a fiber or a wire. Slow withdrawals out of a pure or a

Film entrained by a fiber quickly drawn out of a liquid bath

The thickness of the film entrained by a fiber quickly withdrawn out of a bath of wetting liquid is of interest. For velocities larger than a threshold (usually of the order of 1 m/s), inertia can no

Free coating of pseudoplastic liquids onto a vertical surface

A theory of withdrawal of cylinders from liquid baths

A theory of the amount of liquid entrained by cylinders upon withdrawal from liquid baths is derived for a wide range of cylinder radii. The theory is based on matching curvatures for static and

Thickness of a liquid film adhering to a surface slowly withdrawn from the liquid

When a solid body is immersed in a bath of liquid and withdrawn, a film of the liquid adheres to the solid surface and gradually drains back into the bath when the motion ceases. The relationship

The role of surface rheology in liquid film formation

The role of surface rheology in fundamental fluid dynamical systems, such as liquid coating flows and soap film formation, is poorly understood. We investigate the role of surface viscosity in the

Deposition of Langmuir-Blodgett layers

The behavior of a liquid being pulled out along a vertical plate is discussed, assuming that, in equilibrium, the liquid has a finite contact angleθe. Using a simplified form of the Huh-Scriven
