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…
