Rees DAS, Bassom AP, 'The nonlinear non-parallel wave instability of boundary-layer flow induced by a horizontal heated surface in porous media', Journal of Fluid Mechanics, pp. ISSN () [Refereed Article]. Based on the linear stability, the flow may become unstable to three modes of instabilities: a Tollmein–Schlichting wave in either the upper fluid layer or the lower fluid layer, and an interfacial mode.

These instabilities may be further categorized according to the physical mechanisms that drive by: 5. Interfacial phenomena, viz. roll waves and elastic tremor, are considered in the first part, whereas in the second bounding theory is applied to double-diffusive convection and shear flows.

Roll waves are investigated using shallow-water equations with bottom drag and diffusivity. We explore the effect of bottom topography on linear stability of turbulent flow, followed by an.

Lubricated flow in an oil core is called core-annular flow, or CAF. Typically, waves appear on the surface of the oil core and they appear to be necessary for levitation of the core off the wall when the densities are differ- ent and for centering the core when the densities are matched.

We call these flows wavy core-annular flows (WCAF).
