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…

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…
