The dynamics and stability of thin liquid films have fascinated scientists over many decades:
the observations of regular wave patterns in film flows down a windowpane or along …

▪ Abstract Coating is the process of applying thin liquid layers to a substrate, often a moving
web. Complex coating processes can be approached through examination of their fluid …

The linear stability of variable viscosity, miscible core–annular flows is investigated.
Consistent with pipe flow of a single fluid, the flow is stable at any Reynolds number when …

The linear instability of a surfactant-laden two-layer falling film over an inclined slippery wall
is analyzed under the influence of external shear, which is imposed on the top surface of the …

We present a model for thixotropic gravity currents flowing down an inclined plane that
combines lubrication theory for shallow flow with a rheological constitutive law describing …

Superposed layers of fluid flowing down an inclined plane are prone to interfacial instability
even in the limit of zero Reynolds number. This situation can be explored by making use of a …

Swelling is the process of volume expansion, usually brought about by the intake of water.
One mechanism by which water can be drawn into a material is if the material has less water …

We examine the stability of radially spreading, gravity-driven thin films of power-law fluids,
lubricated from below by another power-law viscous fluid. Such flows are susceptible to a …

The effects of wall velocity slip on the linear stability of a gravity-driven miscible two-fluid flow
down an incline are examined. The fluids have the matched density but different viscosity. A …
