“…Eccentric-cylinder forward-roll coating One of the most intensely researched viscoelastic interfacial phenomena, due to its importance in industrial coating applications, is the variation of coating film thickness (Bonn et al 1995;Huzyak & Koelling 1997;Lee et al 2002) as a function of the processing speed.…”

“…Variations of the problem have since been analysed by various researchers both theoretically (Reinelt & Saffman 1985;Ruschak 1985;Lu & Chang 1988) and computationally (Giavedoni & Saita 1997;Lee et al 2002). Early experimental studies on air-liquid displacement of non-Newtonian fluids were conducted by Bonn et al (1995). Using solutions of poly(ethylene oxide) (PEO) and xanthane, they reported a film thickness increase over that found for Newtonian liquids in the plane flow geometry.…”

We have investigated the role of liquid elasticity in the dynamics of air-liquid interfaces during immiscible fluid displacement flows. Our experimental studies of coating flows with gravity stabilization in an eccentric cylinder geometry for both a viscous Newtonian fluid and a series of elastic Boger fluids have uncovered two new elastically driven phenomena. First, elasticity is shown to create steady, two-dimensional 'sharp interfaces' under creeping flow conditions in forward-roll coating. Digital particle image velocimetry (DPIV) and DEVSS finite element techniques are applied to investigate the effect of gravity on both the flow field and the state of polymeric stresses near the free surface. Secondly, a new class of elastically driven stable substructures is shown to form and persist along the tip, i.e. the centre stagnation line, of the two-dimensional 'sharp interfaces' even after the onset of ribbing.

“…Jiang [4] and Tanveer [5] reviewed recent studies on experimental and theoretical aspects of viscous fingering. Bonn [6] studied the viscous fingering in complex fluids in which the viscosity or the interfacial tension is changed by means of surfactants or polymers. Masami [7][8][9] investigated the viscous fingering of HPMC solution by pushing air into radial and linear Hele-Shaw cells.…”

From the macroscopic point of view, expressions involving reservoir and operational parameters are established for investigating the stability of moving interface in piston-and non-piston-like displacements. In the case of axisymmetrical piston-like displacement, the stability is related to the moving interface position and water to oil mobility ratio. The capillary effect on the stability of moving interface depends on whether or not the moving interface is already stable and correlates with the wettability of the reservoir rock. In the case of non-piston-like displacement, the stability of the front is governed by both the relative permeability and the mobility ratio.
