Energy Method and Stability of Shear Flows: an Elementary Tutorial
Antonio Barletta, Giuseppe Mulone
This paper provides a pedagogical introduction to the classical nonlinear stability analysis of the plane Poiseuille and Couette flows. The whole procedure is kept as simple as pos…
Laminar forced convection characteristics in a round microchannel with shape uncertainty: effect of wall slip
L. A. Sphaier, A. Barletta, M. Celli +3
The shape of a microchannel cross-section is usually affected by a significant uncertainty due to the small hydraulic diameter. Such an uncertainty is indeed present at any scale,…
Anomalous mass diffusion in a binary mixture and Rayleigh-Benard instability
A. Barletta, B. Straughan
The onset of the Rayleigh-Benard instability in a horizontal fluid layer is investigated by assuming the fluid as a binary mixture and the concentration buoyancy as the driving for…
Shape uncertainty analysis of laminar forced convection in a round microchannel with viscous dissipation
A. Barletta, M. Celli, L. A. Sphaier +3
The shape of a microchannel is usually affected by a significant uncertainty due to the small size of the cross-section, comparable with the typical wall-roughness length scale. Su…
Asymptotic behaviour for convection with anomalous diffusion
Brian Straughan, Antonio Barletta
We investigate the fully nonlinear model for convection in a Darcy porous material where the diffusion is of anomalous type as recently proposed by Barletta. The fully nonlinear mo…
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…
