Mixed convection and onset of instability due to asymmetric wall heat fluxes in a porous channel
A. Barletta, M. Celli, P. V. Brandão
The problem of convective instability onset in a horizontal porous channel is explored. The channel's impermeable walls are heated with asymmetric thermal conditions modelled throu…
Wall roughness and viscous dissipation effects in microchannel heat sinks with semicircular cross-section
A. Barletta, M. Celli, P. V. Brandão
A statistical analysis of the wall roughness effect is carried out to determine the impact of the shape uncertainty on the Poiseuille number and Nusselt number of laminar forced co…
Stabilising effect of generic anomalous diffusion independent of the Rayleigh number
Antonio Barletta, Pedro Vayssière Brandão, Florinda Capone +1
This work investigates the influence of a generic anomalous diffusion model on mass convection in a fluid-saturated porous medium, focusing on superdiffusive regimes. A mathematica…
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,…
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…
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…
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…
Rayleigh-Bénard instability of an Ellis fluid saturating a porous medium
Michele Celli, Antonio Barletta, Pedro V. Brandão
Unlike the power-law model, the Ellis model describes the apparent viscosity of a shear-thinning fluid with no singularity in the limit of a vanishingly small shear stress. In part…
