Quasi-logarithmic spacing law in dewetting patterns from the drying meniscus of a polymer solution

, 2012
We report on a periodic precipitation pattern emerged from a drying meniscus via evaporation of a polystyrene solution in a Petri dish. It appeared a quasi-logarithmic spacing relation in the pattern as a result of stick-slip motion of the contact line ...

Formation of liquid menisci in flexible nanochannels [PDF]

, 2008
This paper describes the elasto-capillary formation of menisci at the liquid-air interface in nanochannels that are covered with flexible capping membranes. The equilibrium between the capillary pressure in the fluid and the membrane bending results in a

Filling transition for a wedge

, 1998
We study the formation and the shape of a liquid meniscus in a wedge with opening angle $2\phi$ which is exposed to a vapor phase. By applying a suitable effective interface model, at liquid-vapor coexistence and at a temperature $T_{\phi}$ we find a ...

Liquid meniscus friction on a wet plate: Bubbles, lamellae and foams

, 2013
Many microfluidics devices, coating processes or diphasic flows involve the motion of a liquid meniscus on a wet wall. This motion induces a specific viscous force, that exhibits a non-linear dependency in the meniscus velocity.

Control and ultrasonic actuation of a gas-liquid interface in a microfluidic chip

, 2009
This article describes the design and manufacturing of a microfluidic chip, allowing for the actuation of a gas-liquid interface and of the neighboring fluid. A first way to control the interface motion is to apply a pressure difference across it.

Simulating temporal evolution of pressure in two-phase flow in porous media [PDF]

, 1998
We have simulated the temporal evolution of pressure due to capillary and viscous forces in two-phase drainage in porous media. We analyze our result in light of macroscopic flow equations for two-phase flow. We also investigate the effect of the trapped

Stagnation–saddle points and flow patterns in Stokes flow between contra-rotating cylinders [PDF]

, 1998
The steady flow is considered of a Newtonian fluid, of viscosity mu, between contra-rotating cylinders with peripheral speeds U-1 and U-2 The two-dimensional velocity field is determined correct to O(H-0/2R)(1/2), where 2H(0) is the minimum separation of

The discoid meniscus [PDF]

Journal of Children's Orthopaedics, 2007
Discoid lateral meniscus is an intra-articular knee disorder typically presented in the young population and during adolescence. Different types of meniscal disorders and varied forms of presentation have been reported. The natural history depends on the type of anomaly and the presence of symptoms. Management of the disorder should be directed toward
