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…
