Gill's problem in a sandwiched porous slab
Antonio Barletta, Michele Celli, Stefano Lazzari +1
The classical Gill's stability problem for the stationary and parallel buoyant flow in a vertical porous slab with impermeable and isothermal boundaries kept at different temperatu…
The Boussinesq approximation for buoyant flows
Antonio Barletta
The aim of this communication is to present a simplified, yet rigorous, deduction of the Boussinesq approximated governing equations for buoyant flows. In order to carry out the co…
On the use and misuse of the Oberbeck-Boussinesq approximation
A. Barletta, M. Celli, D. A. S. Rees
The Oberbeck-Boussinesq approximation is the most widely employed theoretical scheme for the study of natural or mixed convection flows. However, the misunderstanding of this appro…
Effects of anisotropy on the transition to absolute instability in a porous medium heated from below
Michele Celli, Antonio Barletta
The emerging instability of a forced throughflow in a fluid saturated horizontal porous duct of rectangular cross section is investigated. The duct is heated from below by assuming…
