Small-Scale Flume Investigation of the Performance of Step-Baffle Drainage Channels in Mitigating Debris Flows

Frontiers in Earth Science, 2022
Drainage channels are widely used for discharging debris flows into deposition basins or rivers. However, the current drainage channel designs for guiding rapid debris flows downstream do not account for the variations of the gullies’ gradient and debris

Turbulent channel flow perturbed by triangular ripples [PDF]

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018
This paper presents an experimental investigation of the perturbation of a turbulent closed-conduit flow by two-dimensional triangular ripples. Two ripple configurations were employed: one single asymmetric triangular ripple, and two consecutive asymmetric triangular ripples, all of them with the same geometry.

Innovative catalytic streamlined carriers with triangular channels

Chemical and Process Engineering: New Frontiers, 2023
The paper presents research on a novel catalytic carrier, called "streamlined structure". The carrier is a short-channel monolith, whose walls are shaped like an airfoil profile (airplane wing). The intention is heat transfer intensification coupled with moderate flow resistance.

Joint Unitary Triangularization for MIMO Networks [PDF]

, 2011
This work considers communication networks where individual links can be described as MIMO channels. Unlike orthogonal modulation methods (such as the singular-value decomposition), we allow interference between sub-channels, which can be removed by the ...
