Rayleigh-Bénard instability in a horizontal porous layer with anomalous diffusion
Antonio Barletta
The analysis of the Rayleigh-Bénard instability due to the mass diffusion in a fluid-saturated horizontal porous layer is reconsidered. The standard diffusion theory based on the v…

Temporal to Spatial Instability in a Flow System: A Comparison
Antonio Barletta
The definitions of temporal instability and of spatial instability in a flow system are comparatively surveyed. The simple model of one-dimensional Burgers' flow is taken as the sc…

Dissipation instability of Couette-like adiabatic flows in a plane channel
A. Barletta, M. Celli, S. Lazzari +1
The mixed convection flow in a plane channel with adiabatic boundaries is examined. The boundaries have an externally prescribed relative velocity defining a Couette-like setup for…
